Deploy using Starman, not FCGI

Testing done:

* Provisioned this onto `lolo`
* Added a new `lolo.musicbrainz.org` server to `lenny`, which is basically the same as `musicbrainz-full`, except it has a different `proxy_pass`
* Changed `lolo`'s `DBDefs.pm` to point to `lolo.musicbrainz.org`

At this point, clicking around on `lolo.musicbrainz.org` (with an appropriate entry in `/etc/hosts`) appears to do the right thing. Also, browsing to `/login` redirected me to a HTTPS end point (though the certificate is invalid, but that's fine) as expected.
