Update config around production-like environments

[ghost]

I understand stuff is changing real soon with #59 but I was struggling with getting staging setup to behave exactly like production in terms of fingerprinting, minifying etc right now.

There are a number of other options that are required in ember-cli if a build exactly the same as --environment production is desired, which i've now added to the readme.

Thanks for improving the README! Unfortunately this is still a pain to do in ember-cli and also other addons are a problem with this approach because they can't be forced to add productionLike assets via the app's Brocfile (ember-faker is an example). Bloats the build but does not change the app's behaviour much of course.

Would be great if you could also add the vendorFiles-property which is needed to add the production like builds for handlebars and ember itself for vendor.js:

  vendorFiles: {
    'handlebars.js': {
      staging:  'bower_components/handlebars/handlebars.runtime.js'
    },
    'ember.js': {
      staging:  'bower_components/ember/ember.prod.js'
    }

Think there's a bunch of issues in the ember-cli repo around multiple environments so hopefully there will be a simpler solution soon.

Just pushed up the vendorFiles addition.

Actually, is adding vendorFiles necessary? Adding it breaking ember build for me.

Ah I don't have handlebars.
