Unnecessarily call to node_load() in fusion_core_preprocess_comment()

fusion_core_preprocess_comment() makes the following call to node_load()

  $node = node_load($vars['comment']->nid);                                                               // Comment is by node author
  $vars['author_comment'] = ($vars['comment']->uid == $node->uid) ? TRUE : FALSE;
  $comment_classes[] = ($vars['author_comment']) ? 'comment-by-author' : '';

This is an unnecessary performance drain as the node object is already loaded in the comment variables. My proposed change is:

  $vars['author_comment'] = ($vars['comment']->uid == $vars['node']->uid) ? TRUE : FALSE;  // Comment is by node author
  $comment_classes[] = ($vars['author_comment']) ? 'comment-by-author' : '';
