Firelocks 101 : Sanity fucking edition

What is an firelock ? A miserable piece of machinery.

- Reviewed the map AND the Asteroid (ESPECIALLY THE RESEARCH OUTPOST) to
redistribute firelocks

The logic is simple. If it's not a Maintenance Airlock and not an
External Airlock outside of very specific exceptions (Disposals,
Artifact Holding), it should most likely have a firelock under it. I've
mostly removed firelocks in ridiculous places (in windows, or out in the
open regarding the Research Outpost) while putting them under a fair
number of airlocks

Other fixes :

- Did basic unfucking to the Research Outpost, nothing structural, but
mostly fixing names
- Added two or three lightswitches missing of long date
- Switched Aux Charging area sprite to the AI placeholder for the
meantime

More map PRs will follow later on, but they'll be different in nature. I
prefer to make my PRs as atomic as possible to make sure we agree on the
basics
