Simplify and streamline animation classes relationship: wxAnimation is the only public class representing an animation and it can be created by both the native wxAnimationCtrl and wxGenericAnimationCtrl using the new public CreateAnimation() method. Replace wxAnimationImplType enum with more flexible type info based check.
