AR view working, settings WIP

- Added the (almost) latest GART dll
- Now the Augmented Reallity view correctly responds to orientation
changed
- Switching to map view also toggles the heading indicator and the 3d
augmented view
- Augmented view tested "in the wild", and confirmed working (with
randomly added coordinates)
- Started working on the settings/about page
- Changed the application tile (phone accent background, white logo)
