Bard Adjustments
(#663)
* Bard Use Refactor
Refactored DiscReady, UseItem, UseAA, UseDisc to allow the bard to use instant aa/item/discs while singing.
* Bard Adjustments
* Fixed an issue in which discs, aa and items would not always properly report ready for a Bard.
* We will now properly ignore Crescendo if the gem is in cooldown.
* Speculative fix for occasionally locking gems when an Insult is cancelled at precisely the wrong moment.
