Remaps the nuke ops shuttle for station docking

* Adjusts the shuttle to incorporate a nice, 2-tile wide docking hatch.
* Drops the viro/xenobio docking arm.
* Adds a door control to allow the teleporter blast door can be operated independently of the airlock blast doors.
* Fixes some leftover arrivals area just hanging around in space.
* Adds a poster specifically for the nuke ops shuttle.
