- Cleaned up the menu/layout (only the ArdRi option works)
- Added new text in the strings.xml
- Added player/score text to the activity_boardui.xml (not dynamic)
- Removed the actionbar from the GUI
- Changed the min. SDK version to 11 (styles.xml code required it)
- Added player turns (white player starts)
- Added handling for device rotation etc. so the game state is kept 
(except during a crash) although there is a bug which causes the 
highlighted piece to not show up as highlighted after a rotation even
though it is active
Removed some test code from BoardUI
Added highlighted images (meaning the piece is active) for
white, black, and king.
Merge branch 'menu' of https://github.com/mariufa/Hnefatafl into BoardBugs
Bug fikset med å gjøre ingenting...?, spent på å se endringene.
