webform support

At present, the "node" support for Better formats does not cover the modified body field used by webforms.

I've used a custom hook_form_alter to deal with this (see below), but it would be great if Better formats could support this widely-used module by default.

The following is simply a copy of better_formats_form_alter() and better_formats_set_node_format(), but looking for the webform format selector instead. It seems to work from an initial test. It doesn't deal with the per-node-type option, as I wasn't using that.

/**
 * Implementation of hook_form_alter().
 */
function mymodule_form_alter(&$form, $form_state, $form_id) {
  // Add Webform support for Better formats module
  // @see better_formats_form_alter()
  if ($form['#id'] == 'node-form' && $form['type']['#value'] == 'webform') {
    mymodule_better_formats_set_webform_format($form);
  }
}

/**
 * Processes formats for webform body fields.
 *
 * @see mymodule_form_alter()
 */
function mymodule_better_formats_set_webform_format(&$form) {
  // Set webform body field.
  if (isset($form['webform']['settings']['format'])) {
    // Get default for new entries.
    $default = better_formats_get_default_format('node', $form['type']['#value']);

    if (empty($form['nid']['#value'])) {
      // Set format to default for new entries.
      $format = $default;
    }
    else {
      // Get existing format for core body field.
      $format = better_formats_get_current_format($form['webform']['settings']['format']);
    }

    // Overwrite the filter form with our own.
    $form['webform']['settings']['format'] = better_formats_filter_form($format, $default, 'node', $form['type']['#value']);
  }
}
