1) Relax requirements as to OpenGL ES ( now only 3.0 required )2) fix a crash in Solving state
Minor tweaks to the 'Prev' buton in Solving state;Relax requirements in the Manifest - now only 'android.hardware.faketouch' supporting device is required, i.e. something that supports basic point-click-drag-unclick. No need for full 'android.hardware.touchscreen' thing with its multitouch silliness.
Add a 'withdraw move' button to the Solving UI state.
Reorganize UI of the Play state.
More support for the 3x3x3 Solver: more of the actual 3x3x3 solver mechanism.
