    actor: Make Actor instantiatable
    
    ClutterActor now has all the API and capabilities for being a concrete
    class:
    
      - layout management, through delegation
      - container implementation and API
      - background color
    
    This means that a simple scene can be built straight out of actors
    without using subclasses except for the Stage.
    
    This is the first step towards the deprecation of most of the Actor
    subclasses provided by Clutter.
