Many status effects aren't updated when going up/down stairs

There are many instances of this. If you go down stairs while on fire, and there's water at the bottom, the fire doesn't go out until you move. If a monster is in "hunting" mode and is stuck in a net, and you go up some stairs, the monster will follow you up the stairs after a few turns but will still be stuck in a net. There's likely too many other examples to list easily. It also appears that going up/down stairs doesn't cost a turn.

This is not a bug, though I guess the status lingering for monsters is

Encountered a similar issue in RapidBrogue with a burning wraith stuck in a spiderweb ("entangled in billowing flames") while I was hasted, which allowed me to get the free "dangling helplessly" hits in.

To clarify, the only bug here is monsters not clearing appropriate status effects when using stairs. In fact, the only example we have yet of this is stuck monsters, which shouldn't really be able to use stairs at all? Maybe that should be fixed instead?
