Popular is a top 10; a Directory lists every listed feed A to Z

- GET /api/popular returns the ten most subscribed feeds. The new GET
  /api/directory returns every feed that may be listed, sorted by name,
  from the same list: everyone counted, you included, never a URL, never
  a private feed or a feed inside an OPML. POST /api/popular/{id} still
  subscribes to anything on it.
- A Directory button sits beside Popular; both open the same list
  screen. The sidebar toolbar wraps rather than squeezing four buttons.
- Tests: the directory is A to Z, Popular is its top ten, Paid Show is
  in neither, and subscribing works from the directory.
