Settings: more specific read and write mode

Browse Source 
For each filesystem interaction be more specific if we want to read from
the file or write to it.

Doing a non-creating read on the loading of the settings file, otherwise
an empty file could be created, and when reading that empty file for the
initial settings I would expect an error (or random data) when reading.
