Flintlock Weapons mod

 The biggest update I've done so far. Adds the new treasure enchantment "cache", which has 2 levels. Each level increases the number of bullets the gun can hold (and the number of times you can shoot without reloading) by 1. Also added some support for adding the flame enchantment onto guns. Modified Zombie loot table to make them occasionally drop feathers, like they used to in the beta editions.
