refs #7 ACRA (Android Crash Reporter Application) integration.
 * ACRA 4.5.0 integrated as of this revision.
 * appcompat_v7_gridlayout library is used as of this revision,
   therefore minSdkVersion could be version 11 again.
 * Layout of levels changed, they no longer use ScrollView as a
   parent view. LinearLayout used plus assigning suitable sizes from
   LevelActivity(e.g. squareSide = screenHeight * 0.097).
   Current design works better when device screen is in portrait mode.

 In next commit we will release version two, Horray!
refs #6 Level nine and release version two.
 * Version two released (see refs #6 logs for history of changes).
   Note: Generated files(R.java and BuildConfig.java) are no longer included.

Enjoy the game!
