Progress with FactoryBandaged.
New, generic bandaged 3x3 class 'TwistyBandagedAbstract'.
Now, (almost!) any bandaged 3x3 can be created by extending this class and implementing one abstract method 'getPositions()'. Almost, because there's still one restriction: currently all cubits need to be one of the 5 allowed types: 1x1x1, 2x1x1, 3x1x1, 2x2x1, 2x2x2....
Preparation for local creation of puzzles: remove the 'ObjectType' enum from TwistyObject class.
