Use https only

[daveyarwood]

Currently we do not support https://alda.io, only http://alda.io.

We should get an SSL certificate, maybe through https://letsencrypt.org, and figure out how to set it up through GitHub Pages so that we support https too.

Then, we should always redirect http => https.

Doing some brief googling, it seems like setting up an SSL certificate is not really supported out of the box if you're hosting your site on GitHub Pages and you have a custom domain.

I might look at moving alda.io to a DigitalOcean droplet and setting up SSL via nginx and LetsEncrypt. The tricky thing is being able to automate deploys like we currently have set up through GitHub Pages, but I'm sure it's doable.

EDIT: yeah, there are a number of ways to do it: https://jekyllrb.com/docs/deployment-methods/

Netlify looks promising.

I started taking a look at Netlify and it's very nice, not to mention free.

I set up https://aldawebsite.netlify.com. From here, it looks like it will be easy to set up alda.io as the custom domain, enable SSL with a single click, and set up continuous deployment from this Git repo.

TODO:

• [x] Fix Google Fonts links, use SSL to remove Mixed Content warning.
  • I assume there must be an SSL equivalent. It might be as simple as changing http to https.
• [x] Fix slack.alda.io/slackin.js link, use SSL to remove Mixed Content warning.
  • It looks like the Heroku site already supports SSL, but the slack.alda.io CNAME doesn't support SSL unless I upgrade to a paid dyno. Lame, but I can't find a free alternative that will work with Slackin and supports CNAMEs with SSL. It's not expensive, so I'll stick with Heroku and upgrade to a paid dyno.
• [x] Point alda.io at https://aldawebsite.netlify.com
• [x] Enable SSL in Netlify UI.
• [x] Set up continuous deployment (via git deploy in this repo) in the Netlify UI.
• [x] Turn off GitHub Pages for this repo?
• [x] Rename repo alda-lang/alda.io (be sure to fix link in https://github.com/alda-lang/alda/issues/293)

Done!
