int_meta 6.x-1.0-beta5

#322365: The module is not creating dynamic meta tags anymore - Fixed a problem where PHP4 didn't like using pass-by-reference variables with call_user_func();.
#328204: Duplicated META content - Was accidentally duplicating information.
#232262: taxonomy support next to node support - Metatag rendering for teasers is now a feature in Drupal 6 that will not be back-ported to Drupal 5 unless I can figure out a good way to do it.
