Bug 5374 (update transaction date when saving biblio) RESENT with small fix

Currently, the plugin marc21_field_005 and its unimarc opponent fill field 005
when this field gets focus. This implies that updating a record without
touching this field does not update 005.
At the same time, a user could accidentally delete a character in the 005 when
having focus. This mutilated field value will be saved however.

I would suggest to add a few lines to ModBiblioMarc in Biblio.pm to ascertain
that adding or updating a record always updates 005 in marc21 as well as
unimarc.
