Adds three flame-themed illegal Mech weapons and more. (#4058)

* Adds three flame-themed illegal Mech weapons. Allows anything using apply_effects to be incendiary and ignite/apply firestacks. Also absolute-paths the spilled fuel effects.

* Removes world << because I'm a good coder honest.

* Why does Git do this for no reason.
