Bug 571527 – gvfsd-http crashed with SIGSEGV in

	Bug 571527 – gvfsd-http crashed with SIGSEGV in
	g_hash_table_lookup().

	As currently written, libproxy's gnome plugin causes intermittent
	gvfsd-http crashes, and I didn't have time to come up with either
	a fix or a workaround. So for 2.26.0 we will fall back to using
	the GConf-based proxy resolver. Hopefully to be fixed for 2.26.1.

	* configure.in: require both gconf and libproxy if building
	--with-gnome

	* libsoup/soup-proxy-resolver-gconf.c: bring this back.

	* libsoup/soup-gnome-features.c
	(soup_proxy_resolver_gnome_get_type): use gconf instead of
	libproxy

	* libsoup/Makefile.am: updates
