Created by: IratePirate

(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
