We need to refactor this a bit to make sure the update routine is triggered properly. Prob we need to use the Migrate object.

As a work arround the routine is now also triggered if the database column count is different then what was expected. As an corrective measure the update is triggered by the config.class.php here :

This should 'idealy' never get triggered...
