handle 001 field

[utnapischtim]

The 001 field holds the control number of the organization creating the record. This means importing a record from e.g. alma means that the control number e.g. mms-id from alma has to be moved to the 035 field. Going from the repository to alma this has to be done the other way around and the 001 aka marcid has to be moved to the 035 field.

if a record is created the marc21 service has to take care that the 001 mmsid is not overridden, but has also to set the 001 with the newly created marcid
