doc: add a custom 404 page

Add a site-wide custom error page for broken references within the site.
Besides giving a better user experience, it's also easier to track
broken links to the site using google analytics (looking for hits to the
404.html page and noticing the referrer.

Note we only "publish" the custom 404.html when publishing the latest
documents (not for released versions) so we always get the latest
left-navigation menu when a 404 error occurs.
