Give a direct download link for the ISO image

We don’t have any right now and that’s open for debate.

The idea behind having no direct link is to avoid making it super easy to download without verifying. Still this will annoy people, see https://twitter.com/FabulousBeasts/status/692751397679427584.

An alternative possibility would be to link to the Torrent file from the release notes for example, as BitTorrent provides the same level of verification than HTTPS.
