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

[Spoodle]

The 90 wire requirement doesn't add any additional challenge, really. I like someone's previous suggestion of it requiring a lens though. Also, maybe there could be a higher energy draw requirement (2500pu/shot?) that'd necessitate using a higher capacity cell to be effective.

These are all critiques, but I like the idea of the PR, and would like for it to succeed
