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

[Dhaidburt]

improvised ranged weapons have always been a super delicate balance on goon (IE. they generally suck):
- zip guns in .22 are pretty slow, awkward and arent used that often iirc.
- slamguns are even slower than zip guns
- bows can do some crazy damage, but it requires the victim to wait patiently for you to draw it

That's a really good point, there's a level of jank missing from the laser rifle right now. Even the RP-5 Macro Phaser has more jank..

Why not the wiring just fries after a certain amount of shots, requiring you to reattach some more wiring? You could do this while it's on your back so you'd be giving up a valuable back slot for easier repairs, and it's not too unreasonable compared to reloading the slamgun or sacrificing inventory space to have multiple slamguns in your backpack.
