Add pretty urls

This adds a new flag namely `--pretty-urls` that when enabled will serve the equivalent
`.html` if it exists.

Very much the same approach that [`netlify`
uses](https://docs.netlify.com/site-deploys/post-processing/).

It can be quite useful when having hrefs like `/about` serve `/about.html`.
