LootSpecHelper

- Updated dungeon loot to show proper ilvl while also allowing for dungeon levels of max hero rank or max vault rank.
- Added enable/disable checkbox and chat command to control targeted loot popups. Disabled status will not persist across logins
- Added reset button and chat command to allow for re-opening of targeted loot popups on a previously targeted boss or current dungeon
- Added targeted loot popup to end of dungeon run to allow for quick comparison of dropped items
- Added functionality to add/delete all above/below ranks. For example if you want an item from LFR Gnarlroot, safe to say you also want it from Normal, Heroic and Mythic and if you delete it from Mythic, you also do not want it from Heoric so that functionality is now built in when you delete one level, all below it also get deleted and when you add one level all above it get added.
- Revamped entire UI to separate loot lists by Boss or Dungeon. Also moved add item button to the top of the list
- Updated raid popup to show ilvl in tooltip for the difficulty currently in

Important Notes:
- Newest version will require your current list to be entirely deleted and rebuilt to not have possible errors.
