Magic Cube

New UI

A few code improvements.

Make the 4 built-in BandagedCuboids use the introduced InitData concept and remove all specific bandaged object classes.

Introduce InitData, a data structure used to initialize a TwistyObject.
Current (optional) members: int[] numLayers, int param [intended: type of the Crazy 3x3 planet], float[][] pos [position of a bandaged cube] )

minor

Improve two things in the BandagedCreator:

- when one minimizes the app and re-maximizes it, now the app remembers the state of the bandaged cube being created
- when one minimizes the app while one of th cubits is marked, it no longer gets marked the second time on re-maximizaton (which was the reason why some cubits sometimes couldn't be unmarked).

Correct a crasher.

Finally fix the bad bug where people could submit impossible records!

Generalize the max number of moving parts and max size of quat group.

Correctly compute bandaged icon's projection angle.
