I've added in some more cumulative damage effects and fixed problems that had arisen with the swing velocity and impact calculations. The bronze colossus can die, unarmed striking fights end eventually now, and I had 13 dwarves with maces beat 13 dwarves with swords (with 2 and 3 dwarves remaining in two tests), so many of the issues seem to be resolved. Several bugs related to ranged weapons should be up within a few days, but I'll probably want to check a few more things here.
