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

[unfunnyperson]

We should add the PTL as a dissassembly part for fun.
Cargo could order a new lens and parts for it.

But the PTL lens would probably do a lot of damage and set people on fire, but it would instantly set the gun on fire, firing again would blow it up on the user.

And now finally traitors have a reason to do something against the PTL.

While this would be funny the first few times, staffies destroying the PTL to build a death ray every round would get old really quick
