- For each post, there's no longer a mandatory Dutch and English

- There's a new table for the links to the articles themselves. These include a

  language code and a foreign key to the post they belong to.

- If an article is available in the active language, but not tagged for the same

  dialect, then it should just show up without any warnings.

- If an article is not available in the active language, only the title should

  show up, but where the short intro text would normally be, there should be an

  explanation that it's only available in other languages, and provide links to
