Security aesthetic overhaul

- Security have been reverted from the muted color red jumpsuits to their old jumpsuits, with some adjustments. They will now also roll their sleeves up instead of unzipping their jumpsuit, because it looks much better when you have armor equipped.

Left is old, right is new: (officer/warden/hos)

Note: I'm not sure whether to re-include the kneepads or not. I was the one who originally added them to our current uniforms, but our jumpsuits no longer have armoring.

- Armor has been changed from dark and edgy to grey and plain like it used to be. This is because the only people who looked good with the previous armor was security, and that was lame considering it was used by the bartender, HoP, and basically every rev in existance. NOTE: this is not a straight revert to old armor and helmets. I have taken what's good from both old and new and mixed them to be more form fitting. Armor will not make you look fat like it used to :+1: 

Same as before, left is old right is new:

- Captain and HoS formal uniforms have been renamed 'parade' uniforms, as they're very lavish and not so much formal as they are swanky dress uniforms for cerimonies.
- Added a formal outfit for the warden and HoS, for maximum bureaucracy. Spawns in their lockers by default.

- Improved berets by adding a single pixel to the north/south sprites.

- Added tactical helmets and tactical armor. They replace the bulletproof vest. These use the old armor sprites we use currently on the live build. They are good against explosions and bullets, but worse against melee and lasers. They are located in the armory next to riot gear.
