Title: Accept both HIREFIRE_* and HEROKU_* config vars

I'm also using the [heroku-autoscale](https://github.com/ddollar/heroku-autoscale) gem, so I want hirefire and heroku-autoscale to share the same env vars for heroku config.
This change lets me configure `hirefire` using `HEROKU_EMAIL` and `HEROKU_PASSWORD` , while remaining compatible with the existing variables.

I personally think `HEROKU_` should be the default, though.
