feed: various object-orientation cleanups

Favor Inbox objects as our primary source of truth to simplify
our code.  This increases our coupling with PSGI to make it
easier to write tests in the future.

A lot of this code was originally designed to be usable
standalone without PSGI or CGI at all; but that might increase
development effort.
