Maintenance fix at medbay, added emergency air and added markings to emergency air supplies.
Added floors with 1,2 and D on them into medbay.
We now have secure smartfridges. More changes:
Changed xeno smartfridge to a secure smartfridge.
Added a chemistry/medical smartfridge for easy chemical storage.
Smartfridge usage now leaves fingerprints.
Secure smartfriges are emagable, by the way!
Medbay, Xenobiology and Virology now have secure smartfridges.
Smartfridges are now hackable. Also fixed a bug where one could not properly access the fridge in chemistry.
