Hyperlink protocol changed: HTTP -> HTTPS (#1)

[drtychai]

Just as the title says; if the domain supported HTTPS, then the protocol was appropriately changed.

The following two three sites were the only ones without TLS support configured:

• wambook.sourceforge.net
• minikanren.org
• blog.ezyang.com

FWIW, I went through and clicked at least one link for each unique FQDN.

Oops, I missed blog.ezyang.com. Sorry for the extra commits!

The book build is now failing on due to a 403 from https://air.mozilla.org/rust-meetup-march-2017/, I'm not entirely sure why; it doesn't seem to be related to the HTTP -> HTTPS change:
