Copy and modify gnome_vfs_uri_list_parse() so that we get a list of string

2004-03-03  Christian Persch  <chpe@cvs.gnome.org>

	* lib/widgets/ephy-node-view.c: (uri_list_parse),
	(drag_data_received_cb):

	Copy and modify gnome_vfs_uri_list_parse() so that we get a list
	of string uris instead of GnomeVFSURIs. Change signature of
	::node-dropped accordingly. Fixes bug #120231.

	* src/bookmarks/ephy-bookmarks-editor.c: (node_dropped_cb):

	Adapt to the changed ::node-dropped signal signature.
