Feature: ember loader now will pass check for AMD compliance

There are libraries out there that will wrap themselves in an AMD module when the `define` function and `define.amd` are defined.

This article http://dailyjs.com/2011/12/22/framework/ highlights that a `define.amd` should be an object. For now, simply setting it to true will allow http://momentjs.com/ to wrap itself in an AMD module for ES6 importing into our app [see here](https://github.com/moment/moment/blob/develop/moment.js#L2923). I will continue to do research to see what this `define.amd` object is supposed to be and get another PR ready when we have the AMD expected object.

Thanks!
