fix pb with bytes field processing: currently when an existing file is edited
and no new file is specified, it finds no value in req.form and so try to
detach the current file, which is wrong. In that case, nothing should be done.
So introduce a new UnmodifiedField exception that may be raised in
field's process_form_value method (catched in field.process_posted).
