This commit became a bit bloated:
- Implemented heal predictions using SuperWoW
- Now caching buffs/debuffs to make querying easier and to pave the way for multiple heal UIs of the same unit
- Added more tracked buffs/debuffs
- SuperWoW can now be a distance provider if UnitXP SP3 isn't present
- Priests will cast Revive Champion instead of Resurrection if the target has Holy Champion and the priest is in combat
- Add "context" special bind, but it only works for party members
Additionally:
- Added new default tracked auras
- Fixed offline players showing missing health bug
- Fixed addon being busted for new characters
- Added help subcommand
