- fix a typo
- make it so mouseover-as-target works properly (Blizzard doesn't send mouseover events if target = mouseover)
- update non-normal units (units that don't receive Blizzard events) automatically every 0.25 seconds.
- Unit namespace for LibDogTag-3.0. For addons that wish to use unit-oriented tags, they'd include this library along with LibDogTag-3.0.
- note: not done yet to any real degree
