function to register a new boxed type ExtensionClass. (pyg_boxed_new): new

2001-06-08  James Henstridge  <james@daa.com.au>

	* gobjectmodule.c (pyg_register_boxed): function to register a new
	boxed type ExtensionClass.
	(pyg_boxed_new): new function to create wrapper instances for a
	particular boxed type (given its typecode).

2001-06-07  James Henstridge  <james@daa.com.au>

	* pygobject.h (pyg_boxed_get): add prototypes for a PyGBoxed type
	that will be used for all boxed types in pygtk (well, I can hope
	:)

	* gobjectmodule.c (pyg_register_interface): new function to
	register interfaces with.  Makes sure I don't accidentally give
	the interface a parent class :).  Also adds a __gtype__ class
	attribute similar to GObject classes.  May also make interfaces
	subclasses of GInterface at some point.
