Title: Add some space transitions checks

Away missions with too many space tiles would make the _setup_map_transition_ proc take too long to finish, making Byond throw a runtime, thinking there was an infinite look

* Away missions space tiles won't be processed for the space cube setting
* setup_map_transitions proc is now set to background if processing too many tiles (prevent Byond infinite loop protection from kicking in)
