Some minor changes in rdf format (thanks to Edd Dumbill), and use

2003-07-10  Marco Pesenti Gritti  <marco@it.gnome.org>

	* src/bookmarks/ephy-bookmarks-export.c: (add_topics_list),
	(ephy_bookmarks_export_rdf):

	Some minor changes in rdf format (thanks to Edd Dumbill),
	and use namespaces in the code.

	* src/bookmarks/ephy-bookmarks-import.c: (bookmark_add),
	(ephy_bookmarks_import_xbel), (parse_rdf_subjects),
	(parse_rdf_item), (ephy_bookmarks_import_rdf):
	* src/bookmarks/ephy-bookmarks-import.h:

	Add an rdf importer.

	* src/bookmarks/ephy-bookmarks.c: (ephy_bookmarks_load),
	(ephy_bookmarks_save), (ephy_bookmarks_init),
	(ephy_bookmarks_finalize):

	Update db to 1.0, import bookmarks from the rdf first time.

	WARNING Backup your bookmarks.rdf file before using this
	and let me know if you get any problems. (esp if you had a
	< 0.7.3 epiphany version).
