The BinLayout should store a pointer to the Container that it is using it as the layout manager. This allows us to fix the API and drop the additional Container arguments from set_alignment() and get_alignment(). This also allows us to add a ClutterBinLayout::add() method which adds an actor and sets the alignment policies without dealing with variadic arguments functions and GValue (de)marshalling.
