Android SDK minimum level and target
Initially I had in view the lowest level possible to make the game accessible to everyone.
However I was led to use features introduced in the level 5 of Android SDK (Android 2.0), and as levels 5 and 6 are no longer available in the workbench, I set the minimum level to 7 (Android 2.1.x).
However I have introduced possibility of using new android functions appeared with android 3.0 and 4.0 (action bar, Holo type themes), and I use android 4.0.3 as target SDK. Thus the one which has version 3.0 or upper of android may use these functions.
