Item Prop Redundancy

[aristotlepenguin]

There are some circumstances where items use descriptions pulled from a prop when there's no reason to do so. If an item's props are comprised of defaults, we ought to leave the prop blank and pull it from the item's definition map. It's a large scale fix and probably should be done after the first item prop related issue on here, the consistency one. However, it will greatly reduce bot startup time and general performance because we won't pull nearly as many items as we did before.
