Prevent PHP Fatal error: memory size exhausted

If I remember correctly, there is a problem recursion in the token module and when there are many fields might the memory limit is exhausted.

We can see this problem in other modules exemple:

The solution is change de code:

   if (module_exists('token')) {
      $form_settings['title_settings']['token_help'] = array(
        '#theme' => 'token_tree',
        '#token_types' => array('node'),
      );
    }

For

   if (module_exists('token')) {
      $form_settings['title_settings']['token_help'] = array(
        '#theme' => 'token_tree',
        '#token_types' => array('node'),
        '#dialog' => TRUE,
      );
    }
