Fix broken HTTPS support

[KyNorthstar]

Currently, navigating to https://fuckingblocksyntax.com/ in Google Chrome results in this error:

There are issues with the site's certificate chain (net::ERR_CERT_COMMON_NAME_INVALID).

Hmm, interesting. Now that GitHub Pages properly supports HTTPS (and this site is configured via CNAME), this should "just work". I'm seeing the same results, though. Will investigate soon.
