[MAP] Increases medbay floor space, adds locks to toilets and fixes #848

- Extends cloning lab, cryogenics room, sleeper room and surgery by two rows to try to ease the amount of shoving during emergencies. It's very frustrating trying to doctor with a horde of patients and volunteers packed into the tiny areas, pushing and shoving trying to treat each other or get treated. Hopefully these two extra rows of tiles will reduce the shoving.

- Adds bolt buttons to toilet stalls so players can AFK, spawn traitor items or absorb genomes in there in peace. Also for fluff, as public toilets have locks.
