Changed the display logic for message author.  New conditional COND:MAIL:LOCAL which activates if we believe a message originated locally.  This currently only detects c_fqdn and we need to modify it to handle all local domains.  If a message originated locally then we display the user name by itself with a link to their profile.  If a message originated somewhere else we display the user name and email address.
