Map Update, Pulse Rifle Change

Map changes:
- Genetics APC fixed.
- Gygax removed from the armory at Fox's request.
- AI chamber reverted at Fox's request.
- Updated admin room.

Pulse rifles may now only be carried on a person's back. Because we
don't allow fun here.

Fancy new L6 SAW icon as well.
