Add welding fuel to chemical dispensers.

[rulib]

The alternative would be to make the welders run on something else like the gas plasma or an acetylene reagent, thus the tanks would still be flammable, and rename the welding fuel into into an appropriate light hydrocarbon that is still flammable but doesn't make giant comedy fireballs that is retained for use as an appropriate chemical precursor.

Like we have two requirements for welding fuel right now: serve as a stand-in for light hydrocarbons in chemistry, and make the tanks explode like bombs.

Hell, maybe the tanks explode TOO much.
