Magic Cube

Move all the strings from objlib to the app.
Upgrade AGP from 8.1.4 to 8.3.2

minor

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

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

Beginning of support for more than one solver per object.

Restructuring for the solvers in the app.

Progeress towards automatically integrating the Algorithmic solvers into the list of solvers in the App.

add new shape category to the main grid list: CUBOIDS.

Fix the association between a RubikObject and its solvers and patterns.

Before, if we rearranged the objects order in the main screen, this would break down.

We no longer distinglish between the different shapes on the basis of number of puzzle walls as there are now the Octahedron and the Barrel both with 8. Now we do it properly, on the basis of the 'shape' part of object's category.
