Configuration Files are Rad

We'll need secret keys to do cool API stuff. This will allow us to load them without keeping those keys in source control.

### NOTE
Message me to get a `config.js` file.
It probably would be better to keep the config data on the server, do whatever you need with it, and pass the results to the client. It puts more load on the server, but if the config data gets passed to the client, anyone could nab the keys out of it.
