Animated Outlet and Slide Transitions

Adds in the ability for transitions to be applied to route changes.  This is done with https://github.com/billysbilling/ember-animated-outlet and only works with named outlets.  Because of this, I had to create an application template in order to apply it to main route changes.  Another requirement is that it only works with explicitly defined views, not virtual ones.  

Conveniently, these transitions play nicely with the existing animations using Ember Animate https://github.com/gigafied/ember-animate.
