TwistyPuzzleLib

Major change: separate the notion of a TwistyObject and its Node. Now,

1) the Node stays when we change objects (this makes transitions faster)
2) it's possible to just create an Object without adding it to the Screen (now app needs to explicitly create the Node and add it to its Screen itself)

Systematic names for the meshes.

Separate the notions of a sticker shape and a sticker color.

simplify sticker/color map.

Progress with serializing object to JSON: cubits.
Only faceColorMap remains now.

Progress with serializing object to JSON: shapes.

Progress with serializing object to JSON: stickers, quats.

Progress with serializing object to JSON: rotations.

Progress with serializing object to JSON: scrambling.

Reorg for writing the JSON

- remove the retarded NODE_RATIO from TwistyObject
- more correctly estimate Cuboid's 'realSize' as an average of their 3 sizes.

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

'IconMode' finished.

1) introduce possibility to move objects, i.e. display them not in the middle of the screen (not fully functional yet)
2) do away with unneeded any more interface 'EffectController' - since ObjectPreRender is the only implementation now.

Remove the 'setupObject()' redundant API.

Move more code to objectlib.

Simplify TwistyObject's API.

Reename ObjectList to a more logical ObjectType.

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

move the resourceIDs from ObjectList to individual object classes.
