Outreach map changes

[PsyCommando]

Massive set of changes to the outreach map, alongside several changes to chargen and etc.

• Added a chargen spawn queue.
• Moved chargen stuff into a more sensible spot.
• Refactored some of the chargen code.
• Added support for sec hud classification.
• Remade map layout a bit in a few places. Not fully finished yet since moving station to space in another PR.
• Changed a bunch of old icons to make more sense with the wall perspective. (newscaster, request console, atm, etc..) Imported them from old europa server.
• Updated a few icons to their bay equivalent.
• Added chlorine canisters.
• Fixed a bunch of invisible icons.
• There's a bunch of commits that might be worth porting upstream. But, accounting for changes that happened upstream meanwhile would be hard.
