.1 atmos map changes

Hopefully this works proper.

The following edits were made;

Atmospherics was cleaned up and Bayified, adding in the pressure suits and so forth as well as one minor change to allow waste to flow into port. The break room was edited to make it cleaner, out of personal preference alone. Xeno and Virology intro hallways were both expanded so they weren't one tile wide. Additionally, both were given a air pipe into it, though Viro's has a actual little closet and pump specifically so Atmos techies can decide when to put air into the dangerous environment etc. Both still scrub into space. Additionally, airlocks around were expanded to be 2x2 in preparation for pushes for Bay cycling, and the fact that it's annoying for engineering. 

I did not add cycling airlocks, that's a headache for another day. Baby steps.

I additionally was not able to test the atmos changes, I'm afraid, as I could not host the map due to a missing world file or some nonsense. However, I get atmos and there should be no issue at all. If there is, I can go back and fix it before we get this live.

... And hopefully this commit works in general, as this is my first go at it.
