Plays one of 3 sounds whenever lightning shield, water shield, or earth shield are removed from the player or the player's earth shield target.

1.3: Thanks to Peef from Mal'Ganis: Updated for Wrath, more efficient earth shield tracking.

1.2.1: Fixed sound not always playing for earth shield on other characters

1.2: Will now play the earth shield sound if removed from the player's earth shield target, instead of just the player.

1.1: updated to work with the new combat log changes in 2.4
