[MERGED PR] Adds a new salvager weapon: The Makeshift Laser Rifle

[unfunnyperson]

I really like the overheating mechanic, the idea of having makeshift weapons just falling apart in your hands has always been part of the appeal to me. As for intended jank, maybe having it need to be cranked in some way after a few shots, similar to how salvagers have to crank their tool or like those laser muskets from fallout 4(god I hated how clunky they were).

The clunkiness of the weapon is intended to come from the heating mechanic + the fact the gun cant fit inside bags. I think they might become a bit too clunky if another factor was added
