Refactored the AA logic so it is more easy to be extended
in future. Also changed from a standard Grid to a Tabbed grid
and prepared a UI for the Vehicle Information values
That will be added in the next commit.
In order to have AA work properly also on production devices
the app needs to be installed from a trusted install source,
which is the Google PlayStore. So the app is now rolled out via
GooglePlay for Beta-Testers.
