PyRNA API support for matrix types as Mathutils matrix (with callbacks) rather then a generic rna sequence of floats.

Any 3x3 or 4x4 rna matrix will automatically be returned as a Mathutils matrix.
This makes useful stuff like multiplying a vector location by an object matrix possible.
 ob = bpy.data.scenes[0].objects[0]
 print (ob.data.verts[0].co * ob.matrix)

Also added mathutils matrix types to the BGE GameObject.localOrientation, worldOrientation

* MT_Matrix3x3 added getValue3x3 and setValue3x3, assumed a 4x3 float array.
* KX_GameObject.cpp convenience functions NodeSetGlobalOrientation, NodeGetLocalOrientation, NodeGetLocalScaling, NodeGetLocalPosition.
* 2.5 python api now initializes modules BGL, Mathutils and Geometry
* modules py3 PyModuleDef's use PyModuleDef_HEAD_INIT, rather then {}, was making msvc fail to build.
* added macros for Vector_ReadCallback, Vector_WriteCallback etc. to check if the callback pointer is set before calling the function.
