Atmos control for the Port-a-Brig

[Grek]

Currently, people in the Port-a-Brig use the atmosphere at the location of the Port-a-Brig. That means if there's no air, they suffocation. What if we could put a gas tank into a slot on it to give the prisoner some oxygen? Or, for particularly unruly prisoners, sleeping gas. Or if you're a mindslave sec, plasma.
