- Add additional treasure type for "unique" items
- Main item dialog now shows the item ability's display name, and also has more space for the item's full name
- (Game) No-ammo missiles (eg slings) are now counted as weapons by shops
- (Dialog Engine) Fix LED groups being drawn when invisible
- Also, missile weapons now use the key skill as well
- Fix guessing of missile types - using the item level didn't work out since the levels weren't what the original code expected, so now it just goes by the name
