Creates a proper area instance for the new engineering shuttle room, to avoid issues with multiple APCs among other things.

Replaces the vent in the fitness room with one which does not show it's connection pipe.
Properly aligns conveyor belt levers on the Research outpost with each other.

Re-locates cameras to improve coverage (no additions), with the purpose of ensuring that the AI can assist in opening main doors (fun times) by seeing both sides.
Affects:
Virology Entrance - Can now see people south of door connecting Viro/Medbay.
Permanent Brig - Can now see the north set of doors by default (would randomly gain coverage, potentially caused by doors closing/opening)
East Central Primary Hallway - Coverage would previously be lost if chemists closed their window shutters.
South Central Primary Hallway - Can now see the south set of doors to the engineering lobby, default coverage of the HoP's and nearby all-access doors (again, coverage would eventually be granted by unknown process)
West Mining Wing - Can now assist in opening both sides of the bridge connecting the wings
Corrects #5157.

Renames the misc. and xeno-research door to simply "Xenobiology Research".
Adds some of the lost equipment back to misc. research.
Adds Wheelchairs with basic driving functionality
Makes crashing into things possible with extinguisher or harm intent
Fixes. Wheelchair is supposed to help the occupant and not the driver, damn it.
Wheelchairs spawn on footless characters
Replaces stool in Examination with wheelchair
Updated changelog
Movement with wheelchair not possible in space
Fixes compile error
Fixes #5160.

Adds doors between the two sets of emergency shutters in the fore primary hallway.

Only reduces the risk of the issue happening (since the doors themselves can be blown up) but also allows for pass-through during breaches in surrounding areas. A decent enough compromise that's used all over the station. Atmos techs can disable vents remotely for a reason.

Teleporter mapping enhancement

Allows teleporters to be mapped in any direction. Set the dir of the teleporter computer to the direction that the hub is in. I.e. if hub is east, set tele comp dir to 4 (east).
Teleporter computer sets up refs to the hub and station so we don't have to search for the other teleporter components every time we teleport.
Applies underlays and overlays to the components to correctly align the connecting cables.
