ray: split object render from object description

This moves the per-object _prepared state into ray_render_object_$type
structs with all the rendering-related object methods switched to
operate on the new render structs.

Since the current rendering code just makes all these assumptions
about light objects being point lights, I've just dropped all the
stuff associated with rendering light objects for now.  I think it
will be refactored a bit later on when the rendering code stops
hard-coding the point light stuff.

These changes open up the possibility of constifying the scene and
constituent objects, now that rendering doesn't shove the prepared
state into the embedded _prepared object substructs.
