Translate the damn pages

[shushugah]

For some pages like

• techworkersberlin.com/press
• techworkersberlin.com/works-councils we should translate them instead of debating whether to show a localized url with English or not.

On other hand, something like an event page should probably not be translated, it would only create confusion about what language the specific event is in. Better support for filtering press_mentions or events by language would be useful tho, as they're already a mixture of specific languages.
