- renamed generic attribute "isValid" to "invalid" since BL_Shader already uses isValid.
- Moved deprecation warnings from CValue 
- removed unused KX_Scene::SetProjectionMatrix and KX_Scene::GetViewMatrix
- Added KX_Scene attributes "lights", "cameras", "objects_inactive", to allow access to objects in unseen layers (before the AddObject actuator adds them)
- KX_Camera deprecated cam.enableViewport(bool) for cam.isViewport which can be read as well.
