Initial dump of BfA compatibility

Updated for:
- SPELL_POWER_* constants becoming Enum.PowerType.*
- Rank no longer existing in return values for UnitAura, UnitBuff, UnitDebuff, UnitCastingInfo, UnitChannelInfo
- UNIT_POWER event becoming UNIT_POWER_UPDATE
- UnitPopupFrames no longer existing
- Removed events: PLAYER_PET_CHANGED, UNIT_MAXPOWER, PET_BAR_CHANGED, UNIT_DYNAMIC_FLAGS
- Texture return value from UnitAura type changing (name -> id)
- All Warlock specializations using soul shards
- Death Knight rune changes

Haven't tested all classes/specializations yet, so I'm sure I missed some stuff.
Probably need to add support for the new circular cooldown wipe flourish added in the base client.
Saw a problem with cooldown flashes being delayed on DK runes becoming available that probably need to be fixed.
