Need to use D5 API for url()

The Drupal 5 backport doesn't send the absolute URL to the social networking site. The module doesn't use the proper Drupal 5 API for url(). On lines 125 and 148 I replaced the url() function with the proper one for Drupal 5. So:

'url' => url('node/'. $node->nid, array('absolute' => TRUE)),

becomes

'url' => url('node/'. $node->nid, NULL, NULL, TRUE),

It seems to work after that, but I haven't checked it out thoroughly.
