 Bug 15232: Advanced Cataloging Editor: Fix translation issues

This patch makes
koha-tmpl/intranet-tmpl/prog/en/includes/cateditor-ui.inc to comply with
Coding guidlines to avoid translation issues: "JS3: Avoid strings which
mix text and markup Text mustn't contain HTML tags."

To test:
- Apply patch
- Verify that code changes are correct (html markup moved out of
  function _(...) )
- Bonus test: Enable syspref 'EnableAdvancedCatalogingEditor' and verify
  that it works as before
