	** Fix for bug #317823

	* em-format-html-display.c: (efhd_get_uri_puri):
	New helper function to dig up uri or puri from the GtkHtml.
	If the object is an image, then pass it as puri or uri, depends
	on the source of the image.
	* em-format-html-display.c: (efhd_html_button_press_event),
	(em_format_html_display_popup_menu): Using new helper function.

Note: New API functions in gtkhtml are required.
