Fixed probability of bonus for Illusioners
Added DEFAULT probability and probability bonus so you don't have to manually change all the entries if you want to make heads rarer/more common
Fixed mob head drop achievements for Zombies, Skeletons, and Creepers, that would be able to drop their heads twice for charged creepers
