Added a bunch of new 1.5 and 1.4.x items to config.yml
 Moved plugin.yml back to resources/, bukkit gets cranky about it..
Fixed data values recognition on potions, enabled selling potions.
Added night vision and invisibility potion variants
Po8Util.stockKey now takes an ItemStack arg, necessary to get dura. All callers changed accordingly.
Small fix for ordering potions (splitStack was doing an explicit parseByte, we actually want forced truncation).
Changed all the new 1.5 items that are constructed to active:0 by default.
