Title: #197: Adds letterSpacing AnimatedAlpha to TextSprite

I added a new property on TextSprite with the changes on #197, seemed simple enough. The only thing I'm not sure about is that I don't know if `getNaturalWidth()` has to be modified as well. Besides that, this change seems to work great on my tests :).
