Pow config for grown-ups

After I posted my Pow running config Python script, my good friend and colleague Nolan Meyers sent over a link to [Powder](https://github.com/Rodreegez/powder), a gem for working with Pow. The list of things you can do with Powder is conveniently listed in the [README](https://github.com/Rodreegez/powder/blob/master/Readme.md).
