Fix for list in template file when using teasers

  if ($display_options == 'teaser') {
    $output = '';
    foreach ($items as $node) {
      $output .= '<li>'. l($node->title, 'node/'. $node->nid);
      $output .= ' - '. $node->teaser;
      $output .= "</li>\n";
    }
    if ($output) {
      echo "<ul>" . $output . "</ul>";
    }
