[MERGED PR] Remove the hygiene motive from RP

[Egregorious]

Still think we should just remove passive decay entirely over a complete removal.

I am in agreement with this take. I like that the motive makes bathrooms a mechanically useful place to visit; I like that the motive is a visually apparent tool to RP with; I dislike having to keep such a consistent eye on my hygiene so often; and I dislike that I feel discouraged to comment on people's stink lines because so many end up getting them passively.

Remove the passive decay, let it be a thing that lowers due to contact with blood, miasma etc. It'd be funnier if more people stunk because the clown went around spraying compost, rather than merely not washing their hands for 20 minutes.
