@mixonic This changes makes an Ember app lookup initializers in src/init. The exported function loadInitializers is called from app code in src/main.js so we could also change the input there to have the right prefix. A few questions:

• What's the best way to have the flag set from the ember feature flag?
• Many apps like the travis app will have addons that add initializers to the app tree. So what we really want, instead of this change, is to call loadInitializers twice from the src/main.js, for example:

loadInitializers(App, config.modulePrefix);
loadInitializers(App, config.modulePrefix + '/src/init');

Another solution is to use both prefixes within this addon so that we can call loadInitializers once in the app code.

Call to loadInitializers in partial-app

Fixes #42
