BGE Bugfixes (mostly in the py api)

KX_PolygonMaterial and KX_BlenderMaterial - Added a print function (would raise a python error on printing)

* Crashes *
KX_GameObject SetParent - Disallowed setting a parent to its self, caused a recursion crash.
KX_MeshProxy "materials" attribute was segfaulting because of my recent change - I was wrong, you do need to check material types (no idea why since they are both PyObject * at the base)
KX_VisibilityActuator - Wasn't initialized with PyType_Ready() making it crash on access (own fault) 

* Crashes because of missing NULL checks *
KX_PolygonMaterial's "gl_texture" attribute wasnt checking for a valid m_tface
KX_GameObject - added checks for GetPhysicsController()
KX_RayCast::RayTest - didnt check for a valid physics_environment
KX_SceneActuator's getCamera python function wasnt checking if there was a camera.
