TwistyPuzzleLib

Add the 7x7 cube.

Simplification.

Introduce the third type of a cuboid's cubit: the edge.
Makes the meshes much smaller!

Correct the way ObejctScale works in the TwistyObjectNode.

Move the main app to the 'J1M1' object creation mode, i.e. create them from the Json files and using the Dmesh fiels as well.

Make it possible for any app descending from the 'objectlib' to use any of the J0M0, J0M1, J1M0, J1M1 modes.

Remove ObjectType and info it held (icons, mesh file, num of scrambles, shortname) from the JSON file.

Remove ObjectType from a few moree places.

Further simplify ObjectType

Make the meshAssociation of the Rotate effect independent of the global MAX_SIZE of any implemented object.
Now only the NUM_OF_AXIS*MAX_NUM_OF_LAYERS of any individual object needs to be <=32 - before the second factor was global, which - because of the recent introduction of the Cube6 - screwed the Gigaminx (!) where NUM_OF_AXIS=6 and GLOBAL_MAX_NUM_LAYERS = 6 now, so 6*6>32 !

Add info about Cube6.
