Adirelle:
	- Found a way to properly identify set items without tooltip scanning so the equipment filter should be more accurate.
	- New item detection: now use our own implementation of GetItemCount that gives distinct counts for distinct equipment items.
	- Added an option not to merge incomplete item stack at merchant's, mailboxes, bank, ... (ticket #29)
	- Typo.
	- Removed the useless ammo/shard filter and reorder slightly the other ones.
	- New item filter should distinguish crafted and enchanted items now. Also added an option to ignore low quality items.
	- Fixed "compare number with nil" error in TidyBags.
