New in V1.12:
Padding option added to interface panel, New Quest Starters category that will make buttons for "This item begins a quest" items, updated item detection mechanism to catch more items
Categories :
The following categories are defined:
Additions : Items that, due to strageness with the Blizzard API, don't show up automatically, even though they should. These are all based on user feedback, so if you come across a usable quest item that doesn't automatically show up, please post it so I can expand the list.
Combines : Outland "Motes" (10), Northrend "Crystallized" (10), and Enchanting Essences (3) (not skill limited, since anyone can combine)
Trades : Ore (5, Requires Prospecting), Cloth (20, Requires Tailoring), Herbs (5, Requires Milling)
Quest Starters : Items that have the text "This Item Begins a Quest"
If anyone has suggestions for other categories, please post them. They are very easy to add, and the configuration page will generate the checkboxes for them automatically.

V1.15 (29050)
- Reformatted some code, cleaned things up a bit. Expanded some commenting. Removed unused code
- New button creating code to optimize the addon. Buttons that don't change are not "recreated" each cycle.
- Rewrote the way the inventory is scanned to eliminate multiple loops. Keyring and Inventory are treated as bags now
- Removed the old (pre V1.10) profile variables.
- Included localization updates from Xandokan, and a couple of items that weren't triggering buttons (because of the way WoW displays them)
V1.14 (27853)
- Added "Quest Starter Notification", alerts you when you pick up an item that starts a quest
- Quest Starter Items will now be marked with a green "*" where you would see quantity text for stackable items

- Check for validity of itemLink passed to QuestClicksItemHasUseClause
