	* configure.in: check for libgnomeui-2.0. Added version
	requirements (>= 2.10.0) for libgnomeui and gnome-vfs.

	* plug-ins/uri/Makefile.am
	* plug-ins/uri/uri-backend-gnomevfs.c: if libgnomeui is available,
	call gnome_authentication_manager_init() so the URI plug-in can
	access sites that require authentication.

	(this needs more hacking so packagers can build both versions of
	the uri plug-in at the same time, since they will want to make the
	libgnomeui dependency optional)
