Subject: use the more portable encoded_item format for exported items - but
 with added attributes so we can use it as a reasonably complete item backup.
 The encoded_item format gives us extended author and owner information in
 case we need to probe them to bring the entry back. It also contains taxonomy
 entries. Importing and/or recovering will best be accomplished in chunks. It
 could take some time and some memory to chew through this.
