Ember.Select shouldn't trigger change for when content is an empty array-like obejct
The previous check for triggering when content was empty relied on
the falsiness of `[]` but would incorrectly trigger change when the
content was an Array-like object whose proxied `length` was 0.

Specifically this would cause issues with setting the `contentBinding`
of a Select to the `DS.Model.find` values that are empty initially
setting the Select's `selection` from whatever the current value is to
`undefined` when change was triggered on an empty content.

Asynchronously, data would return and the content would become populated
but the selection value had already been unset.

App.container was not meant to be a public API

It appears that people are starting to use
App.container.lookup as the public API for
globally getting other controllers outside of the
router or other controllers.

This was not intended to be a public API.

Instead, you should trigger events on a route
(or a parent route), which have access to
`this.controllerFor`.

Example:

    App.ApplicationRoute.extend({
      events: {
        search: function(term) {
          this.controllerFor('search')
            .set('term', term);
        }
      }
    });

    App.SearchField = Ember.TextField.extend({
      insertNewline: function() {
        var term = this.get('value'),
            controller = this.get('controller');

        controller.send('search', term);
        this.set('value', '');
      }
    });

Events sent to the controller will bubble up to
the current route, and then up the route hierarchy
