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.
