Bug 6678 - Fix some problems with the standard NORMARC framework

- Almost all fields are displayed as expanded in the cataloguing screens,
  because hidden=0 when it should be -1
- Koha-specific fields need to be translated
- some unnecessary punctuation should be removed
- problem with encoding - æøå not displayed correctly

- created a new database  with all nb-NO sample files, no errors reported
- checked the cataloging frameworks for displaying problems
- saved record and created an item - all koha specific fields translated
No problems found.
