Subject: [PATCH] Update method to use the new ID system, which replaces
 linkdate primary keys.

creation and update dates are now DateTime objects.
Since this update is very sensitve (changing the whole database), the datastore will be automatically backed up into the file datastore.<datetime>.php.
