[PR] adds aerosol reaction to golem death

[zjdtmkhzt]

I definitely prefer golem wizards over fireball or transform wizards. Golems are way more interesting and have more variety, with the entire chem system.
And yes, propellant is kind of dumb in how it works, but for golems I think it would be fine.
Alternatively, we could buff the amount of chems that golems inject on hit, so that they could apply disease reagents properly in one hit.

(Also, acid glasses are also super dumb, but that's another issue.)
