TG: Updated the barman's shotgun, it acts like a double-barrel now, and he can saw

it off.
Added Khodoque's new shotgun sprites.

Added my new gasmask sprites. Removed emergency gasmasks, as the distinction is
non-existent.

Very slightly reshuffled some mask stuff around, but it's still godawful.
Medical masks are now /obj/item/clothing/mask/breath/medical

Removed the define for HALFMASK, as it was completely unused.
