BGE Python API (small changes)

- Make BGE's ListValue types convert to python lists for printing since the CValue GetText() function didnt work well- printing lists as [,,,,,] for scene objects and mesh materials for eg.
- Check attributes are descriptor types before casting.
- py_getattr_dict use the Type dict rather then Method and Attribute array.
