//truncate summary if it is longer than 550 characters, remove forced return if that is the only thing in the summary - used on news display pages.  The truncate is needed because we can't truncate data in the Summary Field directly (within the Article Manager user interface);  the removal of the forced return is needed because Article Manager prefills that as a default and you can't remove it from within the interface.
