Add new ammo effects to item factory
Lit torches set enemies on fire
Add flaming effect to wide technique attacks

check remaining momentum before calling plswim()
minor fix to scentmap, added more colors to scentmap

butcher: preserve mtype on meat. iteminfo: "Smells like <original mobtype>", for
players with carnivore, or scentmap, or cheating bastards
