Fork of [Ember-Intl](https://github.com/ember-intl/ember-intl) to support our [YAML format](https://git-aws.internal.justin.tv/web/web-client/blob/master/i18n/translations/en-us.yaml). This only affects the transformation and bundling part of Ember-Intl. Any of the formatters stuff is loaded through the main Ember-Intl (which has its bundling features disabled because this addon takes care of it). 

Differences:
* Transforms Web-Client's Smartling YAML file on app build (transforms meta-properties to normal key/value format)
* Converts translations to Javascript files which are loaded asynchronously. This right locale is set by Rails when rendering `index.html`.
