Add Netlify configuration.

- The netlify.toml file explains how to build this site for production
  and deploy previews.
- The Makefile has some commands to make building the site slightly more
  user friendly, try typing `make help`.
- The Gemfile includes all the dependencies exported from GitHub Pages.
  This site might not need all of the but I don't have the knowledge to
  exclude the unused ones.
