Update the ClutterBox API and structure

Browse Source 
ClutterBox is meant to work like the HTML boxing model: it has a margin and
a backgrdound color, and every child actor is added with a pack type and a
padding. The ClutterBoxChild structure holds the child actor, the padding,
the packing type and the allocated coordinates for the actor.
