Feature: Make hubcap less dependent on config

[VersusFacit]

This script requires a carefully made environment variable be present to run. It'd be nice to wrap variables in such a manner that permits using this script even when that env variable isn't present. That would be helpful for test runs. Right now, it requires an unreasonable amount of hacking to run the main script outside of a heroku cluster (and in time, we'll want to move away from Heroku in general, it seems).
