Set version to 1.15.0

Fix error when compiling the Pinetime using the Docker image.
If done with Docker, the container does not trust the /sources
folder, leading to a blank response of the command that grabs
the git commit `git rev-parse --short HEAD`.

```
fatal: detected dubious ownership in repository at '/sources'
To add an exception for this directory, call:

        git config --global --add safe.directory /sources
PROJECT_GIT_COMMIT_HASH_SUCCESS? 128

BUILD CONFIGURATION
-------------------
    * Mode : Release
    * Version : 1.3.0
    * Toolchain : /opt/gcc-arm-none-eabi-10.3-2021.10
    * GitRef(S) :
    * NRF52 SDK : /opt/nRF5_SDK_15.3.0_59ac345
    * Target device : PINETIME
    * Build DFU (using adafruit-nrfutil) : Enabled
    * Build resources : Enabled
```

If the `git config --global --add safe.directory /sources` is
added to the Dockerfile, the problem is solved and the hash is
added correctly.

+# Simple Weather Service
+
+## Introduction
+
+The Simple Weather Service provides a simple and straightforward API to specify the current weather and the forecast for the next 5 days.
+It effectively replaces the original Weather Service (from InfiniTime 1.8) since InfiniTime 1.14.
+
+## Service
+
+The service UUID is `00050000-78fc-48fe-8e23-433b3a1942d0`.
+
+## Characteristics
+
+## Weather data (UUID 00050001-78fc-48fe-8e23-433b3a1942d0)
+
+The host uses this characteristic to update the current weather information and the forecast for the next 5 days.
+
+This characteristics accepts a byte array with the following 2-Bytes header:
+
+ - [0] Message Type : 
+   - `0` : Current weather
+   - `1` : Forecast
+ - [1] Message Version : Version `0` is currently supported. Other versions might be added in future releases
+
+### Current Weather 
+
+The byte array must contain the following data:
+
+ - [0] : Message type = `0`
+ - [1] : Message version = `0`
+ - [2][3][4][5][6][7][8][9] : Timestamp (64 bits UNIX timestamp, number of seconds elapsed since 1 JAN 1970)  in local time (the same timezone as the one used to set the time)
+ - [10, 11] : Current temperature (°C * 100)
+ - [12, 13] : Minimum temperature (°C * 100)
+ - [14, 15] : Maximum temperature (°C * 100)
+ - [16]..[47] : location (string, unused characters should be set to `0`)
+ - [48] : icon ID 
+   - 0 = Sun, clear sky
+   - 1 = Few clouds
+   - 2 = Clouds
+   - 3 = Heavy clouds
+   - 4 = Clouds & rain
+   - 5 = Rain
+   - 6 = Thunderstorm
+   - 7 = Snow
+   - 8 = Mist, smog
+
+### Forecast
+
+The byte array must contain the following data:
+
+  - [0] : Message type = `1`

+Apps can be refreshed periodically and reacts to external events (touch or button).
 
 ## Interface

-it does not need to override any of these functions, as LVGL can also handle touch events for you.
-If you have any doubts, you can always look at how the other apps function for reference.
 
-### Continuous updating

-If your app needs to be updated continuously, you can do so by overriding the `Refresh()` function in your class
+The **destructor** cleans up LVGL and restores any changes (for example re-enable sleeping).

-taskRefresh = lv_task_create(RefreshTaskCallback, LV_DISP_DEF_REFR_PERIOD, LV_TASK_PRIO_MID, this);
+that will call the method `Refresh()` periodically.
+
+## App types
+
+There are basically 3 types of applications : **system** apps and **user** apps and **watch faces**.
+
+**System** applications are always built into InfiniTime, and InfiniTime cannot work properly without those apps.
+Settings, notifications and the application launcher are examples of such system applications.
+
+**User** applications are optionally built into the firmware. They extend the functionalities of the system.
+
+**Watch faces** are very similar to the **user** apps, they are optional, but at least one must be built into the firmware.
+
+The distinction between **system** apps,  **user** apps and watch faces allows for more flexibility and customization.
+This allows to easily select which user applications and watch faces must be built into the firmware
+without overflowing the system memory.
+
+## Apps and watch faces initialization
+
+Apps are created by `DisplayApp` in `DisplayApp::LoadScreen()`.
+This method simply call the creates an instance of the class that corresponds to the app specified in parameters.
+
+The constructor of **system** apps is called directly. If the application is a **user** app,
+the corresponding `AppDescription` is first retrieved from `userApps`
+and then the function `create` is called to create an instance of the app.
+
+Watch faces are handled in a very similar way as the **user** apps : they are created by `DisplayApp` in the method `DisplayApp::LoadScreen()` when the application type is `Apps::Clock`.
+
+## User application selection at build time
+
+The list of user applications is generated at build time by the `consteval` function `CreateAppDescriptions()`
+in `UserApps.h`. This method takes the list of applications that must be built into the firmware image.
+This list of applications is defined as a list `Apps` enum values named `UserAppTypes` in `Apps.h`.
+For each application listed in `UserAppTypes`, an entry of type `AppDescription` is added to the array `userApps`.
+This entry is created by using the information provided by a template `AppTraits`
+that is customized for every user application.
+
+Here is an example of an AppTraits customized for the Alarm application. 
+It defines the type of application, its icon and a function that returns an instance of the application.
+
+```c++
+template <>
+struct AppTraits<Apps::Alarm> {
+  static constexpr Apps app = Apps::Alarm;
+  static constexpr const char* icon = Screens::Symbols::clock;
+
+  static Screens::Screen* Create(AppControllers& controllers) {
+    return new Screens::Alarm(controllers.alarmController,
+                              controllers.settingsController.GetClockType(),
+                              *controllers.systemTask,
+                              controllers.motorController);
+  };
+};
 ```
 
-With `taskRefresh` being a member variable of your class and of type `lv_task_t*`.
+This array `userApps` is used by `DisplayApp` to create the applications and the `AppLauncher`
-Remember to delete the task again using `lv_task_del`.
+to list all available applications.
-The function `RefreshTaskCallback` is inherited from `Screen` and just calls your `Refresh` function.
+
+## Watch face selection at build time
+
+The list of available watch faces is also generated at build time by the `consteval`
+function `CreateWatchFaceDescriptions()` in `UserApps.h` in the same way as the **user** apps.
+Watch faces must declare a `WatchFaceTraits` so that the corresponding `WatchFaceDescription` can be generated.
+Here is an example of `WatchFaceTraits`:
+```c++
+    template <>
+    struct WatchFaceTraits<WatchFace::Analog> {
+      static constexpr WatchFace watchFace = WatchFace::Analog;
+      static constexpr const char* name = "Analog face";
+
+      static Screens::Screen* Create(AppControllers& controllers) {
+        return new Screens::WatchFaceAnalog(controllers.dateTimeController,
+                                            controllers.batteryController,
+                                            controllers.bleController,
+                                            controllers.notificationManager,
+                                            controllers.settingsController);
+      };
+
+      static bool IsAvailable(Pinetime::Controllers::FS& /*filesystem*/) {
+        return true;

+
+If your application is a **system** application, go to the function `DisplayApp::LoadScreen`

 The case will be the id you gave your app earlier.
 If your app needs any additional arguments, this is the place to pass them.
 
-If you want to add your app in the app launcher, add your app in [displayapp/screens/ApplicationList.h](/src/displayapp/screens/ApplicationList.h) to the array containing the applications and their corresponding symbol.

+If your application is a **user** application, you don't need to add anything in DisplayApp,
+everything will be automatically generated for you.
+The user application will also be automatically be added to the app launcher menu.
+
+Since the list of **user** application is generated by CMake, you need to add the variable `ENABLE_USERAPPS` to the command line of CMake.
+This variable must be set with a string composed of an ordered list of the **user** applications that must be built into the firmware.
+The items of the list are fields from the enumeration `Apps`.
+Ex : build the firmware with 3 user application : Alarm, Timer and MyApp (the application will be listed in this specific order in the application menu).
+
+```cmake
+$ cmake ... -DENABLE_USERAPPS="Apps::Alarm, Apps::Timer, Apps::MyApp" ... 
+```
+
+Similarly, the list of watch faces is also generated by CMake, so you need to add the variable `ENABLE_WATCHFACES` to the command line of CMake.
+It must be set with the comma separated list of watch faces that will be built into the firmware.
+
+Ex: build the firmware with 3 watch faces : Analog, PineTimeStyle and Infineat:
+
+```cmake
+$ cmake ... -DENABLE_WATCHFACES="WatchFace::Analog,WatchFace::PineTimeStyle,WatchFace::Infineat" ...
+```
 
 You should now be able to [build](../buildAndProgram.md) the firmware
 and flash it to your PineTime. Yay!

-/**
- * Different weather events, weather data structures used by {@link WeatherService.h}
- *
- * How to upload events to the timeline?
- *
- * All timeline write payloads are simply CBOR-encoded payloads of the structs described below.
- *
- * All payloads have a mandatory header part and the dynamic part that
- * depends on the event type specified in the header. If you don't,
- * you'll get an error returned. Data is relatively well-validated,
- * so keep in the bounds of the data types given.
- *
- * Write all struct members (CamelCase keys) into a single finite-sized map, and write it to the characteristic.
- * Mind the MTU.
- *
- * How to debug?
- *
- * There's a Screen that you can compile into your firmware that shows currently valid events.
- * You can adapt that to display something else. That part right now is very much work in progress
- * because the exact requirements are not yet known.
- *
- *
- * Implemented based on and other material:
- * https://en.wikipedia.org/wiki/METAR
- * https://www.weather.gov/jetstream/obscurationtypes
- * http://www.faraim.org/aim/aim-4-03-14-493.html

+# Refactoring needed
+
+## Context
+
+The [PR #2041 - Continuous time updates](https://github.com/InfiniTimeOrg/InfiniTime/pull/2041) highlighted some
+limitations in the design of DateTimeController: the granularity of the time returned by `DateTime::CurrentDateTime()`
+is limited by the frequency at which SystemTask calls `DateTime::UpdateTime()`, which is currently set to 100ms.
+
+@mark9064 provided more details
+in [this comment](https://github.com/InfiniTimeOrg/InfiniTime/pull/2041#issuecomment-2048528967).
+
+The [PR #2041 - Continuous time updates](https://github.com/InfiniTimeOrg/InfiniTime/pull/2041) provided some changes
+to `DateTime` controller that improves the granularity of the time returned by `DateTime::CurrentDateTime()`.
+
+However, the review showed that `DateTime` cannot be `const` anymore, even when it's only used to get the current time,
+since `DateTime::CurrentDateTime()` changes the internal state of the instance.
+
+We tried to identify alternative implementation that would have maintained the "const correctness" but we eventually
+figured that this would lead to a re-design of `DateTime` which was out of scope of the initial PR (Continuous time
+updates and always on display).
+
+So we decided to merge this PR #2041 and agree to fix/improve `DateTime` later on.
+
+## What needs to be done?
+
+Improve/redesign `DateTime` so that it
+
+* provides a very granular (ideally down to the millisecond) date and time via `CurrentDateTime()`.
+* can be declared/passed as `const` when it's only used to **get** the time.
+* limits the use of mutex as much as possible (an ideal implementation would not use any mutex, but this might not be
+  possible).
+* improves the design of `DateTime::Seconds()`, `DateTime::Minutes()`, `DateTime::Hours()`, etc as
+  explained [in this comment](https://github.com/InfiniTimeOrg/InfiniTime/pull/2054#pullrequestreview-2037033105).
+
+Once this redesign is implemented, all instances/references to `DateTime` should be reviewed and updated to use `const`
+where appropriate.
+
+Please check the following PR to get more context about this redesign:
+
+* [#2041 - Continuous time updates by @mark9064](https://github.com/InfiniTimeOrg/InfiniTime/pull/2041)
+* [#2054 - Continuous time update - Alternative implementation to #2041 by @JF002](https://github.com/InfiniTimeOrg/InfiniTime/pull/2054)
