Add translated news

Issue from: https://jira.typo3.com/browse/T3ACG-5

As an editor I want to be able to create localized news.

An easy solution could be, to use the functionality "related news". Best way would be, to have an option to assign a flag icon / label to the news, to represent the other language. This should be not a complete language overlay, but the news text could be localized.
