fix for scrambling shape-shifting cuboids. Before when scrambling e.g. the CU_242, we would sometimes 'hit air' (try to rotate a layer which does not have any cubits in it)

Algorithmic solvers (at least the 3x3 beginner and the Kilominx) seem to be working now.

progress with Algorithmic solvers. Seem to solve all right now; but still problems with which cubits it lights.

fixes for Algorithmic solvers (but those still do not work correctly!)

a dialog to interrupt too long solves

Add the 'interrupt()' API to all solvers
Add the 'start/stopSolving' notification to ResultScreen

Initial support for Algorithmic Kilominx verifier and introduction of it into the App.

Do not call the Kociemba solver on an already solved position.

Integration of the Algorithmic solver 'SolverAlgorithmicCUBE3' with the app pretty much done.

3x3 position validator finished; what's left is compute the quat table knowing the position is correct.
