Re-introduce 'callback arguments' to API

I have searched the issues and the git commits, but could not find a reference as to why this was dropped nor could I find an (open) issue of a similar request.

I propose to re-introduce the callback arguments to the API, so that you could do something like:

/**
 * Implements hook_nodewords_tags_info().
 */
function nodewords_custom_tags_nodewords_tags_info() {
  $objects = nodewords_custom_tags_get_objects();

  if (count($objects)) {
    foreach ($objects as $object) {
      $tags[$object->name] = array(
        'callback' => 'nodewords_custom_tags_callback',
        'callback arguments' => array(
          'name' => $object->name,
          'type' => $object->type,
          'title' => $object->title,
          'description' => $object->description
        ),
        'context' => array(
          'allowed' => array(
            NODEWORDS_TYPE_DEFAULT,
            NODEWORDS_TYPE_NODE,
            NODEWORDS_TYPE_PAGE,
          ),
        ),
        'label' => $object->title,
        'templates' => array(
          'head' => array(
            $object->name => NODEWORDS_META,
          ),
        ),
      );
    }
  }

  return $tags;
}

This is a module (nodew)rds_custom_tags) we developed for a customer where you are presented with an interface to create any additional metatag 'on the fly' without the need for development.

Patch for this in attach.

Cheers,

mlc.
