Added flare guns, both civilian and syndicate
-Shoot flares to light up a blackout, or just use them normally
-Shoot flares to light up people (if you're a tater tot)
-Shoot flares because you have nothing better to do
-Flares now correctly change your l_color so you glow red when holding one
-Added a fancy storage box for flares (also in the autolathe)
-Changed the way emergency toolboxes work: they now have a weighted chance to pick 1 of 3 lighting items, either a flashlight, a box of flares, or a single flare
-Added a storage box for flare shells, as well as a way to craft flare shells and flare shells to the autolathe
-Added a dedicated atmos tech locker, which includes some equipment, an RPD, and the regular flare gun
-Added the syndicate flaregun job item for the atmos tech: embeds flares in people and sets them on fire. Also fires shotgun ammo
-COMING SOON: Map changes to include the atmos lockers. Currently they are just code
