Merge pull request #2 from Baystation12/master

Repo update
Map update, swaps Medical Red cross signs to the unironically sickly green kind. Also readds air-distro pipe connection to xenobiology and virology as I had added before, but was lost in a previous botched merger.
Merge branch 'master' of https://github.com/Gamerofthegame/Baystation12
Lawyer map fix
Changes medical doors; Storage general medical instead of surgery for chemistry, reception made a glass door so receptionists can see behind them.
Grants security maint access again, Detective security access again, allows two roboticists to spawn at the start of the round instead of just one and removed chef's access to the morgue. Kept Hydro's, though, because they can plant-clone people and that makes sense. All tested, works out perfectly fine.
