Configure multiple basedir

Make available multiple targets for basedir in configuration.

Yeah, I've thought that I'd add NODE_ENV based package.json lookup to handle this in the future. I don't know what the best way is but there definitely needs to be a way to use multiple environments.

Thinking about a config that looks like this.

"promethify": {
    "basedir": "src",
    "hostname": "local.dev",
    "port": 8089,
    "production: {
            "basedir": "src",
            "hostname": "cdn.yourwebsite.com",
            "outputDir": "out",
            "outputDeployPath": "static/project/releases",
            "port": 8089
     }
  }

Every property that is in the NODE_ENV property would override those from the main promethify config block. Thoughts?
