Pants Slot, Again

[alsoandanswer]

From previous PR:

• Fixes Quick Equip (Thanks, Matt)
• Fixes Loadout Preview, will override uniforms properly now
• Turns shirts into uniform items, so you can attach accessories to them

This also fixes the issue of people spawning in shirtless if they didn't attach properly to the pants.

Additions:

• Shifts suspenders, leather chaps, and kneepads to be pants accessories.
  (This fixes the issue of accessories staying even without pants, e.g. assless chaps)
  (In future, hip holsters are to be added to this accessory list)

Anyway, that's the long and short of it. Have fun.
