- Change theme to 'Book' based on Sphinx pydata theme. It supports dark/light
modes. Looks more modern and better defaults/options.
- Add logo on the top left corner.
- Add menu to go to repository, view page source, edit page source, and report
issue on current page.
- Don't repeat 'FreedomBox Authors' in authors text and copyright text. Show
only once as suggested by the theme.
- Use theme option to show license link instead of overriding the template.
Tests:
- After building the theme, all options work as expected.
- Footer appears as expected.
