TwistyPuzzleLib

IAP part 6: new 'Present' object effect.

scramble,solve,win: license.

Preparation for Mixup Cube: take advantage of the recent bump in MAJOR_VERSION number and change the format of basicAngles to int[][] 'per-axis-per-layer' [ Mixup Cube has different basicAngle in its middle layers (8) - and different in its edge layers (4) ]

Convert Ulti, Jing, Pyra, Diamond, Dinos, Redi, Skewbs, Ivy & Rex to the new scheme where the quaternion group is computed automatically.

Further simplify ObjectType

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)

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

Relax objectlib's requirements: it can be displayed not only on top of a DistortedScreen, but any DistortedFramebuffer.

progress with off-center objects.

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.
