Create a model loader structure which can be used to pass callbacks down from the renderer code. This will allow us to have the render do some processing on the loaded data at appropriate points and let us make the actual loading code generic. In the first instance, pass down the aliashdr_t padding value required by the renderer. Note that to remove a circular dependency introduced in the headers, I had to stop including render.h in model.h/gl_model.h and that change propogated some more changes to includes across the tree...
