Returns true if the spell is available to the player's current specialization and talents. This does not check any immediate circumstances that would prevent the casting action itself; only that the spell is available within the constraints of active specialization/talent choices.
Used by BlizzardUI to determine the drawing of several class-specific power indicators such as Eclipse and Burning Embers.
