kill old 'load http 0 now=0' debug.

2005-01-18  Not Zed  <NotZed@Ximian.com>

	* em-format-html.c (emfh_gethttp): kill old 'load http 0 now=0' debug.

	** See bug #70563.

	* em-utils.c (emu_set_proxy, emu_proxy_setup)
	(em_utils_get_proxy_uri): make sure the init code is called from
	main thread (gconf usage), and add locking for data consistency.
