Added 'A Day in the Life of an Ember Developer'

First part (25 minutes) is very interesting imo.
He talks about different data-binding design patterns, pros and cons, and their corresponding libraries. He compares Backbone, Ember, Angular and React. Very high level, but very interesting.

The second part is about the tools and workflow of an Ember developer. Also interesting, only if you work or familiar with Ember.js, so less relevant to FEDs as a whole.
