- fixed: Multipatch textures may not set up their patch references until all textures have been loaded.

If done earlier they will not be able to detect overrides of sprites and graphics which are not part of the PATCHES lump. There was some fudging code to work around this problem but it was only partially working.
Now these textures only collect the texture name and use type during setup and resolve them after all textures have been created.
