B14001 - Stinking clouds in bonesfiles

Incorporate a fix from <Someone> that resets the timestamp on
stinking clouds left in bones files.  This does allow the cloud's ttl to
restart.  Extended it to reset the player_inside flag.

Then noticed that the only placed that called in_out_region was domove().
Added calls when changing levels (which causes player_inside to be set
correctly if the cloud covers the location where the player starts on the
bones level), teleporting, and inside hurtle_step.  There are still other
places that fail to call in_out_region, which others may choose to tackle.

I split out the remaining stinking cloud bug reported in the same e-mail
into a separate betabug.  That one probably cannot be addressed without
changing the level file format to track the creator.
