Map fixes, tiny changes

Fixed some small issues with the map such as a wall in one of the maintenance doors and removed some APC's that didn't need to be there in the first place. Added a nanomed to medbay for general use.

Also Nexis, someone reported the AI cameras as being fucked and sending people to different locations. For example clicking on EVA East somehow brings you to the courtroom, Captain's quarters brings you to the morgue, etc.

Is this a result of the manual merge or something I fucked up? I didn't edit anything with EVA/courtroom/where cameras send you so...
