Magic Cube

Bump versionCode to 42 (forgotten before)

Fix the Solver

make numLayers into an int[] (preparation for Cuboids)
Caution: because of previous changes to cubit order in cube, the Solver is broken!

Simplify TwistyObject's API.

Reename ObjectList to a more logical ObjectType.

Simplify ObjectList: now there's just one object per size.

Remove all files that have been separated into a new library 'objectlib'

Prepare the 'objectlib' package to be separated into a library module

Refactoring: split the 'objects' package into two, 'objects' and 'objectlib'.
The point: we're going to need to move the 'objectlib' stuff into its own library module, and that's because we're going to create a new app module which needs access to it.

Move the TwistyObject.retCubePosition() to the solver.
