Bug 24314: Update de-DE MARC21 frameworks for updates 28+29 (May and November 2019)

Bug 24314: Update de-DE MARC21 frameworks for updates 28+29 (May and November 2019)

This updates the MARC framework files in the de-DE (German) installer
to the latest MARC standard. The files also include some translation
changes and fixes.

Files have been generated using the po files on translate.koha-community.org.

To test:
- Run the de-DE installer on a fresh database
- Verify that all files are installed without errors
- Verify that the frameworks are correctly in place

MARC21 files load without problems, no qa errors.
Loaded into 'en' install (delete fw then load) all frameworks look good.
