Huge thanks to Kastle for helping me disect this behavior.
- The Unbreakable NBT tag is not the only source for determining if an item should be treated as unbreakable. The damage NBT is also taken into account.
- Custom item options must be processed in an ascending order.
- Multiple conditions may be necessary for an item to be selected.
- Conditions do not have to be exact. See the comments in CustomItemTranslator for an explanation.
- Added a test so we don't break this behavior in the future.
