Panels node body form element needs a filter

Currently panels_node_form adds a body element, but doesn't allow input format to be associated. Luckily it's a one line fix!

  if (!empty($type->body_label)) {
    $form['body'] = array(
      '#type' => 'textarea',
      '#title' => check_plain($type->body_label),
      '#rows' => 10,
      '#required' => TRUE,
      '#description' => t('The teaser is a piece of text to describe when the panel is listed (such as when promoted to front page); the actual content will only be displayed on the full node view.'),
      '#default_value' => $node->body,
    );
    $form['format'] = filter_form($node->format); // Now we can set the format!
  }

Let me know if you want a patchfile.
