Fixes the wounding system

This fixes the autoheal bug, which was being caused by the wrong wound types being used, such as tiny bruises for bullet wounds.

Also separates out the sharp flag into sharp and edge flags, so that things like bullets can cause cuts instead of bruises, which makes a big difference for bleeding, in addition to the wound descriptions.


Is absorb supposed to be applied here? It seems like it is being applied twice, first here and again in apply_damage().
