Move the control of object scaling out the objectlib.Thee xact way the object is scaled needs to be decided in the app, as only the app knows that e.g. in the Rubik main screen, if it is a square, then obejct needs to be a bit smaller than in case of Config screen (if that one happens to be a square)
main: license.
Fix projection matrix with which the puzzles get rendered: make it independent of the aspect ratio of the underlying surface.
Small things.
Fix the solver (after rearranging the faces of the cuboids)
Fix problems with TwistyObjectNode 'object scale' property.Now this property is not part of the Node at all, but its initial value passed to the object in its constructor.
Correct the way ObejctScale works in the TwistyObjectNode.
new API to make is possible to adjust default scale factor in each TwistyObjectNode.(and use it in Tutorials, where the object needs to be smaller)
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)
