Re-organize tutorial list so that we can pull this one from JSON files.
Improve the behaviour of the Config and Tutorial activities when in the 'PopUpMode'. Also, remember the current object in the COnfig activity so that when we put it to the background and resume - the object stays.
Fix setDefaultRotation() when changing an object; do it at exactly the right time when the 'old' object has already disappeared, but the new hasn't been attached to the Nodee yet.
Include the info about 'numFaces' of a puzzle in the jsons.Based on this, and the recently introduced 'DEFAULT_ROTs' to the basic Shape classes, rotate each object in the Config so it looks attractive.
Introduce 'Simple' and 'Nice' meshes.
In the 'magic' app, ObjectType is now only used in RubikObject and RubikObjectList classes and nowhere else.This is a major step towards being able to download objects from an online repository.
Progress with ConfigScreen.
Beginnings of the ConfigActivity.
