regions vs long worm tails

Browse Source 
If any part of a long worm is within a posion gas cloud region,
include it just once no matter how many segments are inside.  The
tail will take harm from poison gas, but only once rather than for
repeated for every segment inside the region.

Unlike with detection, show long worm tail if hero is adjacent to
it in a gas cloud region and would see that tail segment if the
region wasn't inhibiting visibility.
