Add default padding to ClutterBox

Browse Source 
To avoid using a ClutterPadding each time you add an actor to a ClutterBox
when you want the same padding around each child, you can now set the
default padding. The API is pixel-based, since it's a commodity function,
and will affect only clutter_box_pack_defaults().
