"Fixes" #5228

Fixes #5228
Expanded the Research outpost room a bit. It is now possible to refill the supply line with air (or less healthy options).
Moved the scrubber 'behind' the filter line to allow recycling gases in the room, rather than have it direct gases directly into space.
Makes the scrubber port actually have some use, would previously equalize with space (leaving it empty).

Additional:
Cleans up some interior areas of the Research outpost, that were in space/outside on the asteroid.
A previously replaced floor tile under a door had turned into space. Corrected.
Adds windoor/glass protection around a disposal inlet that kept throwing me into space during testing...
