www: support listing of inboxes

We will still return a 404 by default to '/' for compatibility
with users of Plack::App::Cascade or similar.  Inboxes are
sorted by modification times to help users detect activity
(similar to the /$INBOX/ topic view).

New configuration options:

* publicinbox.wwwlisting - configure the listing type
* publicinbox.<name>.hide - hide a particular inbox from the listing

See changes to public-inbox-config.pod for full descriptions
of the new options.
