Title: Link to GitHub and to the doc's own CC0 license

This adds a small footer with a sentence that links to this GitHub repository, and mentions that the document itself is released under a CC0 license.

This seems non-substantive and fine to add in-place. I'll merge a bit later today, barring any :-1:'s.
