Bug 14636: Item search - improving display

- Changes "Publication Date" to "Publication date"
  in the CSV export
- Fixes 'no JavaScript fallback' display to match
  the normal display
  - only show 'by' when it's UNIMARC and an author
    exist
  - show copyrightdate if publicationyear is empty

To test:
- Turn of Javascript in your browser before you
  item search. This will activate the alternative
  display.
- For MARC21:
  - Verify that the author displays when existing
    and no 'by' is shown.
  - Verify that the publication date is now shown.
- For UNIMARC:
  - Verify that 'by' only displays when there is
    an author to display.
  - Verify that the publication date is still
    shown.
- Try the CSV export.
- Verify that the CSV header now reads 'Publication date'.
