Split the interactive parts of the message display out of EMFormatHTMLDisplay
to a new GtkHTML subclass named EMailDisplay, and have EMFormatHTML create an instance of that. EMailDisplay will handle link clicking, mousing over URIs, popup menus, and interactive search. This makes EMFormatHTMLDisplay and EMailReader more lightweight. Clean up more of the EMFormat stack. svn path=/branches/kill-bonobo/; revision=37346
