	* configure.in: check for gnome-keyring.

	* plug-ins/uri/uri-backend.h
	* plug-ins/uri/uri-backend-wget.c
	* plug-ins/uri/uri-backend-gnomevfs.c: added "plugin_name",
	boolean "run" and "run_mode" parameters to uri_backend_init().

	* plug-ins/uri/uri-backend-gnomevfs.c (uri_backend_init):
	initialize the gnome authentication manager only when called
	interactively from "run". Also call gimp_ui_init() when using the
	auth manager, since recent versions seem to require an already
	initialized GTK+. When running noninteractively and gnome-keyring
	is available, implement the needed GnomeVFS authentication
	callbacks ourselves and ask gnome-keyring directly.

	* plug-ins/uri/uri.c: pass the additional parameters to
	uri_backend_init().
