Ken Hughes 4335811695 Python API
----------
Second and final part of MTex API changes.  Added support for new attributes for MTex World objects, stricter checking of attribute types for materia/lamp/world MTex objects, setters for lamp.textures and world.textures attributes, and updated documentation.
