cruser_id and crdate modified when versioning
When a change is made in a workspace, a copy of the record is made (the new version until it is published). On that copy the
cruser_id field is set to the user who triggered this new version. The
crdate field is also changed to the time when the version was created. When the version is published, these become the new values for the live record.
We thus lose the historical creation information about this record. It may be of limited value, but I still think that it is wrong to overwrite it.
