LP#1826890: set page title for Statistical Popularity Badges admin page

To test
-------
[1] In the browser client, navigate to Local Administration -> Statistical
    Popularity Badges
[2] Note that the web browser's tab header doesn't display a title for the
    page, just the URL.
[3] Apply the patch and reload the page. This time, a page title should
    be dispayed in the browser's tab header.
