Make undo and file loading without UI work

Phew, that wasn't easy... lots of digging through history to understand why code is like it is... Also, the window manager relinking in blo_lib_link_screen_restore was never executed (I think) because WM is recreated during file read and was NULL at this point. Now we need to run it, so we simply pass old WM. Things are working quite stable now.
