XZ by default and JSON

We’ve implemented two oft-requested features today:

The download links now default to .tar.xz versions of archives
There is now a JSON file with the release information located in
https://www.kernel.org/releases.json. If you’ve been screen-scraping
the front page, please use this instead.

If you have any other feature suggestions, please send them to
[email protected].
