[imp] link to show/hide deleted messages (patch 2)

[Jan Kuipers]

The patches were created for FW3 (cvs) code. The function should be as  
follows:

function showDeleteLinks()
     {
         if ((!$GLOBALS['prefs']->getValue('use_trash') &&
             !$GLOBALS['prefs']->getValue('use_vtrash') &&
             is_null($GLOBALS['imp_search']->isVINBOXFolder())) ||
             $GLOBALS['prefs']->getValue('delhide') ||
             $this->_showdelete) {
             $ret_array = array('purge' => true);
             $ret_array['hide'] = ($this->sortby() != SORTTHREAD);
         } else {
             $ret_array = array('hide' => false, 'purge' => false);
         }

         return $ret_array;
     }
