Small map changes and fixes

(Note. Tried adding to the changelog but whenever I did it fucked up the formatting somehow and turned it into the old ugly version, none of these changes are that huge so I suppose it doesn't matter)

-changed wide open area in maint SE of medbay and fixed the broken
catwalks
-made theatre backroom one tile wider for consistency
-added vents to auxiliary cyborg station and made it slightly larger to
accommodate them

-moved a mouse out of the wall in surgery overflow and moved the
disposal pipes into the maint shaft
-changed airlock SW of medbay, airless plating to normal plating and
additions of warning signs
-turned the maint area east of the break room into a connecting hallway
so the doors being there might make sense
-removed jutting out wall in Security east maint
-removed some window panes from courtroom observation
-fixed Sec disposal outlet
-fixes to Virology break room cameras
-fixed areas next to Security pod
-moved courtroom observation's air alarm
-renamed dormitories cameras
-moved theatre apc so it's actually in the theatre area zone
-moved the theatre piano so it doesn't glitch into the window
-changed both external airlocks in east and west sec maintenance to be
more consistent with the station's style (i.e. 3 or 4 tiles)
-changed some unnecessarily reinforced walls near courtroom into normal
walls
