Hide reset button when no filters are shown

Patch and install file (stupid CVS doesnt allow me to create a diff for new files if i dont have commit access).

/**
 * Implements hook_update_N().
 *
 * Alter the module weight so that it fires after views_filters_selective, thus
 * allowing us to hide the reset button if no filters are shown.
 */
function views_filters_reset_update_6001() {
  $weight = db_result(db_query('SELECT weight FROM {system} WHERE name = "views_filters_selective"'));
  if (empty($weight)) {
    $weight = 0;
  }
  $ret = array();
  $ret[] = update_sql('UPDATE {system} SET weight = %d WHERE name = "views_filters_reset"', $weight++);
  return $ret;
}

yes, the db update doesnt replace the arguments when it displays the query. I tested it and it worked just fine.
