Disable WYSIWYG on export text area

The code '#wysiwyg' => FALSE, will disable any conforming wysiwyg on the export text area. I think it's a useful addition to this module:

  $form['export'] = array(
    '#type' => 'textarea',
    '#title' => t('Node export code'),
    '#default_value' => $code_string,
    '#rows' => 30,
    '#description' => t('Copy this code and then on the site you want to import to, go to the <em>Node export: import</em> link under <em>Create content</em>, and paste it in there.'),
    '#attributes' => array(
      'wrap' => 'off',
    ),
    '#wysiwyg' => FALSE,
  );
