Changes for version 0.22.0 - 2021-05-29

Reorganized the nav and footer links. There are now fewer of them, and the nav links focus on content, while the footer focuses on metadata.
Added a "Colophon" section to the About page, including links to credit the original site and logo designers, as well as the typeface and icons.
Added the "generator" meta element to the header to report the version, since it, too, has been removed from the footer.
Added /tags/, with the search form defaulting to searching tags, and the tag cloud, since it does not appear on the home page on mobile.
Increased the line size of search results and list tables.
Added a search form to the Users page, and moved the list of letters to search to a horizontal list.
Opened up the spacing in block quotes so that the icon doesn't crowd the text. Applies to error, warning, and success blocks, too.
Knocked 40px off the height of the header on mobile devices.
Added OpenGraph/Twitter unfurl support to all pages. Should make excerpts look nicer for links posted on social media.
