-- new script action:
PromoteUnit. The named character will immediately adopt an advanced class based on their current class--even if they are not at the minimum level normally required to promote to that class.
-- new item: Book of Power. Promotes the user immediately upon use. Requires Book of Power mastery to use, which all characters now automatically gain upon reaching level 10.
-- new item graphic variant: Book Black.
-- added three Books of Power to the Vengeance of Emma Strider campaign in challenging locations; one in the Bandit Fortress Outer Wall Battle, one in the Battle with Ebon Raban, and one in Clash at the Mines Entrance.
-- created a second promotion option for Emma and Sabrina: Liberator. Gives fewer stat bonuses overall than Champion, but provides +1 to maximum movement and takes 2 off the energy cost for Motivate, Inspire, Place Snare Trap and Place Iron Jaw Trap.
-- added some really neat little visual effects accompanying a character promotion in battle.

-- fixed: the game wasn't actually changing character sprites upon promotion.
-- fixed: the game was splitting damage popup text across two lines for amounts exceeding 99.
