Legejo 1.22.0

• Following a shelf. A shelf someone shares with you has a Follow
  button. Books that come onto a shelf you follow are then announced above
  your library, with the shelf, how many and their titles, and the number
  shows beside Shared shelves in the sidebar. On the shelf itself, the new
  ones are marked New. Opening the shelf counts as having seen them, and
  Mark as seen clears them all at once.
  • Each shelf you follow has an Atom feed of its own, for a feed reader:
    an address only you have, which needs no login and stops working when you
    stop following, or when the shelf is no longer shared with you.
• Your reading, to take elsewhere. The Account page gives Reading as
  CSV (Goodreads): the books you have read, are reading or want to read,
  with ratings, the date you finished and your shelves, in the form that
  StoryGraph, BookWyrm and Goodreads take in when importing.
• A new password without mail. An admin can make a password reset
  link for a user on the Admin page, under Users, and pass it on; it works
  once, for a day. When no admin can log in, legejo reset-password <user>
  run on the server (with Docker Compose: docker compose exec legejo legejo reset-password <user>) prints such a link. Both are noted in the system
  log.
• The export on the Account page is now headed Export your library.
• The Legejo Cookbook has three new recipes: Following a Shared Shelf,
  Taking Your Reading Elsewhere, and Helping Someone Who Has Lost Their
  Password.
• Upgrading: nothing to do. A table is added for the shelves people
  follow.
