Subject: [PATCH] config.inc.php: - new config option $CONF['language_hook']  
 Hook function to override or add translations to $PALANG.   Example hook
 function included (commented out).

common.php:
- honor $CONF['language_hook']

scripts/postfixadmin-cli.php:
- honor $CONF['language_hook']
- add TODO - language shouldn't be hardcoded to english

This implements my feature request at
