Host //rust-lang.org over HTTPS

[frewsxcv]

It is possible to host a GitHub Pages hosted website that has a custom domain over HTTPS. I did this for my website using this tutorial and it didn't take too long.

I asked about this a few minutes ago on IRC and @steveklabnik basically just said it hasn't been done yet, which is fine. I didn't see an existing issue open for this so if allowing HTTPS is something that is planned, then I figure it might be good to open a GitHub Issue to track the progress.

It looks like rust-lang/rust#13180 is also open (which I apparently also commented in a few months ago) so if that's a better place for discussion, this can be closed

I agree that rust-lang/rust#13180 is where discussion on this should be happening, so closing in favor of that, but thanks for the report!
