python api for collection add()/remove()

Added a group example
 C = bpy.context
 ob = C.active_object
 bpy.data.groups[0].objects.add(ob)

- add_to_group and rem_from_group now take optional scene and base flags and deal with updating the object & base flags
- operators that add objects to groups were setting ob->recalc= OB_RECALC_OB; looks like its not needed.
- previously add() ignored python args, now add and remove are called like any other FunctionRNA from python.
- made the pyrna api use tp_getset's for collestions active/add()/remove()
