Remove reference to NRF Softdevice in CMake and documentation.

Update documentation.
Remove Asserts when starting advertising to prevent crash (known bug).
Set version 0.5.0.

+## BLE connection and time synchronization
 At runtime, BLE advertising is started. You can then use a smartphone or computer to connect and bond to your Pinetime. 
 As soon as a device is bonded, Pinetime will look for a **CTS** server (**C**urrent **T**ime **S**ervice) on the connected device.
 
@@ -223,7 +209,7 @@ Here is how to do it with an Android smartphone running NRFConnect:
     - Select server configuration "Current Time Service" and tap OK
 * Go back to the main screen and scan for BLE devices. A device called "PineTime" should appear
 * Tap the button "Connect" next to the PineTime device. It should connect to the PineTime and switch to a new tab.
-* On this tab, on the top right, there is a 3 dots button. Tap on it and select Bond. The bonding process begins, and if it is sucessful, the PineTime should update its time and display it on the screen.
+* If a CTS server is found, the Pinetime should update its time with the time provided by the server.
 
 ### Using Linux and bluetoothctl
 * Ensure that your bluetooth controller is enabled and working fine. I've tested this on a x86 Debian computer and on a RaspberryPi 3.
