Log Message:
-----------
2.5 Python api
- rearranged modules bpyui -> bpy.ui, bpy -> bpy.data, remove bpydoc
- new module bpy.types, stores a list of all struct types
- added __rna__ attribute to types - eg bpy.types.World.__rna__ so you can access the rna data from a type. (so bpydoc.structs isnt needed anymore)
- removed unused subtyping method (use python subclassing rather then C PyTypeObject)
