Magic Cube

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

If an object has more than 8 colors, in the solver's SetupPosition screen display the bitmaps in two rows.

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

Launch the verifier first, and only then the solver selection dialog :)

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.

Properly define and separate the interface between the App and the 'solver' part of the objectlib. Move the 'position verifiers' to the objectlib.

Unify the position verifiers (for verifying if a manually set position for solving is possible!)

Integration of the Algorithmic solvers into the App.
