Bug 24223: (QA follow-up) Do not copy to other languages

By majority on Bugzilla, we dont want to have the existing text in all
translatable languages.

Note: Removing the news_123 as code here, switching to OpacNav now.
Another report should handle/improve the use of code, assuming that
it is meant to provide some form of grouping. There is now confusion
between the fields code and location.
