Add a key called 'module' to acvititystream service definition array

When defining an activity stream service there is no indication of the module that defines or owns the service. I'd like to propose adding a key called 'module' to the definition. e.g. for the activitystream_feed module:

function activitystream_feed_activitystream_services() {
  return array(
    'feed' => array(
      'module' => 'activitystream_feed',
      'type'  => 'feed',
      'name'  => t('Feed'),
      'verb'  => t('posted'),
      'icon'  => drupal_get_path('module', 'activitystream_feed') . '/feed.png',
    ),
  );
}
