* Fixes a topic exploit in sleepers.
* Based on feedback from this thread: http://www.ss13.eu/phpbb/viewtopic.php?f=42&t=3789
 * Removed the med-kit from the labor camp.
 * Changed the sleepers in the labor camp so that they weren't as efficient as the station sleepers, stopping them from being used by prisoners to escape.
 * Added an extra sleeper and sink to the room.
 * Removed the syndicate space suits on the abandoned mining station, replaced it with an alien suit and hat.
