[tutorial] show how to embed audio files as <audio> tags

[movepointsolutions]

Hi everyone,
I plan to serve my tribute album .flacs along with .txt Markdown lyrics
A good point to discuss in the tutorial would be, how to construct whole website from static files.

Thanks for the input! I'll see what I can add.

@movepointsolutions I created an example repository: https://github.com/xyproto/algernon-example-site

If it is useful enough, I can perhaps make it into some sort of tutorial.

Please test.

There was a typo in the commit message for 8dfa4f7. That commit closes a different issue.

Please test if https://github.com/xyproto/algernon-example-site is a better example for how to use Algernon.
