Default Settings using different key than Readme Instructs

[ianstarz]

In the readme it says to configure this way:

window.App = require('app').default.create({
  deviseEmberAuth: {
    // ...
  }
});

However, in the index.js file the get setting key uses the deviseSimpleAuth prefix:

    var getSetting = function(app, setting) {
      var prefixedKey = "deviseSimpleAuth." + setting;
      return app.getWithDefault(prefixedKey, defaults[setting]);
    };

One or the other should be updated but I'm not sure which. Thanks!
