- Rewrote "spell cast" detection, previously written for "detect extends". Detect extends should be a lot more robust as a result, though I still get some of my "asserts" in feral.
- Added "Last Raid Recipient" as a buff target. This will auto-set its bar target to the raid member that was the last target for a matching player's spell. Great for healer abilities like Beacon of Light, Lifebloom, Earth Shield, etc.
- Deprecated "Spell Usable" as a bar type. I've left support in for people already using it, but as Victory Rush now grants a buff when it's usable, that's a much better way to watch that ability and Spell Usable has confused many people
