'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.
