Bards:

Added new level 20 Bard Song: Cassindra`s Chant of Clarity.
Bards defensive skill made exactly the same as a warriors.
Changed it so that the bard spell Denon's Desperate Dirge to increase damage by 10pts per level over 45. Also made it so the spell does 20% more damage using the Puretone discipline.
