Merge branch 'master' into warn-on-prerelease-version

* Fix support for logos as urls

Sphinx since 4.0 appears to support html_logo to also contain urls.  As
a consequence, the other themes in sphinx appear to be just using the
new logo_url variable, and in this theme that fixes support for it, too.

* Add backwards compatibility and add favicon_url
