Title: FlxMultiSprite, a sprite with animations from multiple spritesheets.

FlxMultiSprite is a subset of FlxSprite which allows animations from multiple spritesheets to be used in the same sprite.
Decided to put it in flixel.animation and not in addons because for it to work changes to FlxAnimationController were needed (removing inline from functions to be able to override them)
