Update links to use https:// where it is supported. There's probably a lot
more that could be fixed, but these are the core ones I found (especially
the download links in order to prevent MITM attacks). Note that there are
some fb.me links that will redirect to http:// even while accessed over
https://, but this seemed like the best way to fix those for now.
NOTE: Only non-third-party files were modified. There are references to
http:// URLs in vendored/third-party files, but seems appropriate to fix
upstream for those rather than editing the files.
Also, copy one image locally to the blog, as it was hotlinking to a site
that did not support https://.
Last, use youtube-nocookie.com instead of youtube.com for video embeds,
as the former doesn't try to set a cookie on load (privacy enhancement).
