MiliUI Tooltip

New
- Units with restricted information inside instances, such as enemies in dungeons, raids, and Mythic+, now use the redesigned tooltip layout instead of the default Blizzard tooltip. Name, level, classification, quest progress, owner, threat, and Mythic+ Enemy Forces still appear.

Fixes
- After you moused over a unit whose target name was hidden, some item tooltips could show text on top of other text until you reloaded the UI. For example, on raid loot chests, the description overlapped the "Contains one of the following items" list. This no longer happens.
- When the item comparison tooltips switched sides, they could cause a Lua error. They now reposition correctly.
