	* plug-ins/uri/uri-backend.h: added backend methods
	uri_backend_init() and uri_backend_shutdown().

	* plug-ins/uri/uri.c: call them around using other backend
	functions (both in query() and run()).

	* plug-ins/uri/uri-backend-gnomevfs.c: moved init()/shutdown() of
	GnomeVFS into the new backend methods. Create the list of
	supported protocols dynamically. Get rid of one translatable
	string.

	* plug-ins/uri/uri-backend-wget.c: implement the new methods as
	empty stubs which always succeed.
