Added support for animation instance classes (also known as animation blueprints) in skeletal mesh cosmetics.
The property bUseLeaderPose has been deprecated. You can use the new AnimationMode instead: this allows either leader pose or animation instance class. Existing cosmetics will be updated when they are loaded in the editor.
Added a new BoltUI module for UI-specific classes.
Renamed BDButton -> BLAdvancedButton and moved it from the example map to the BoltUI module.
