Mythic Dungeon Lockouts

Adds an information window beside the dungeon journal, listing the current seasonal dungeons and whether you have already looted them on mythic in the current weekly lockout.
Red = you have already looted the dungeon on mythic difficulty.
Green = you have not yet looted the dungeon on mythic difficulty.

You can also have it list past seasons' or expansions' dungeons and their mythic lockouts by changing the dropdown at the upper right of the Encounter Journal's Dungeons tab.  After changing the dropdown you might need to close and reopen the encounter journal to refresh this lockout list (default key: Shift+J).

If it is not listing the current season's dungeons, be sure to change the Encounter Journal's dropdown to Current Season.
