2002-01-15  Jeffrey Stedfast  <fejj@ximian.com>

	* mail-display.c (on_set_base): New callback to handle the
	set_base signal.
	(on_url_requested): If the base_url is set, prepend it to the data
	url (we don't want to do this for cid urls or part urls tho).
	(mail_display_init): Initialize md->base_url to NULL.
	(mail_display_destroy): Free the base_url.
	(mail_display_initialize_gtkhtml): Connect to the set_base signal.
	(on_link_clicked): If the base_url is set, prepend it to the url
	string passed to us from gtkhtml.
