initial public-inbox-httpd implemenation

This is meant to provide an easy starting point for server admins.
It provides a basic HTTP server for admins unfamiliar with
configuring PSGI applications as well as being an identical
interface for management as our nntpd implementation.

This HTTP server may also be a generic Plack/PSGI server for
existing Plack/PSGI applications.
