Gibs now rot and generate miasma (#41782)

* Gibs now rot and generate miasma

🆑 coiax
add: Gibs will now rot if not cleaned, and produce small amounts of miasma, approximately
equal to a quarter of a corpse.
/🆑

Miasma is fun. Gives the janitor more of a reason to do work. It will only become
dangerous if you have a lot of gibs in a small space. So better keep those Hopline shutters
open.

* Rot component, for things that rot

* Whoops

* No longer processes, so doesn't need to stop
