SSoverlays performance tweaks (#3390)
changes: SSoverlays only creates the our_overlays and priority_overlays lists separately and when they're actually used. This should remove a lot of unused lists as priority_overlays is relatively unused. SSoverlays is now FIFO. SSoverlays now uses large Cut() operations instead of continuously truncating its processing list. SSoverlays is no longer a processing subsystem. Performance tweaks to add_overlay() SSoverlays no longer tries to re-process atoms that have already forcibly compiled their overlays (like human-types).
