Farting mechanic

[Alliostra]

Farting makes you fart a 1-tile large cloud similar to the clouds created by smoke powder.
They contain 2 to 3 units of liquid fart, whatever you ate / drank last, stuff it decays into, and some weird reagents at times, less if you didnt eat anything
Runs on a small timer of maybe 10 seconds so the hallways dont get filled with farts.

This is already a genetics mutation

EDIT: other than the liquid farts bit. But there happens to be a not-well-known way to solidify farts. If that's what you're into.

Make frozen farts usable
I want people to slip on frozen fart floors

i changed the toxic_farts mutation to be reagent cloud based
