connect to button_press_event and iframe_created events of GtkHTML widget

2001-03-22  Radek Doulik  <rodo@ximian.com>

	* mail-display.c (mail_display_new): connect to button_press_event
	and iframe_created events of GtkHTML widget
	(html_button_press_event): new signal handler, runs popup on
	address fields and on links, later we should add popups for images
	and maybe some more? any ideas?
	(html_iframe_created): new signal handler, takes care of
	connecting to button_press_event of all iframes
	: plus bunch of empty methods for popup menu items - to be
	implemented

	* mail-format.c (write_address): revert back to raw HTML text,
	store name and email to Text objects, workaround gtkhtml tables
	bug (to be fixed soon ;-)
