Steps to reproduce:
1. The Admin UI NG is the default start page of Opencast since 2.0
2. The Opencast Media Module (/engage/ui) can only be found by users that know that the media module still exists.
Expected Results:
There should be a button/link in the Admin UI that forwards to the engage media module.
