inside unknown jammed doors.

would not correctly affect grid/items in grid.
- Fixed bug where stinking cloud would not do enough
damage.

providing wrong information.
- Fixed bug where thorny bushes would injure you
while standing in them as well as moving through them.
- Fixed bugs where objects and monsters would be
placed in trees and rubble.
- Fixed bug preventing you crossing trees/rubble.
- Reorganised human monsters, so that 'p's are now
priests (including paladins), 'q's are now mages
(including rangers), 't's are now thieves and
warriors, and ensuring that all human monsters
and uniques are distinguished (Since there are so
many). Regularised 'h', 'l', 'o', 'O', and 'T'
monsters to match.
