Title: Use id accessor when fetching Model#id

Using the bracket syntax is discouraged for fetching ids. The id is copied directly as a property to the model.

http://backbonejs.org/#Model-id

I had issues when using their example of:
```js
var Meal = Backbone.Model.extend({
idAttribute: "_id"
});
```
I ran the test suite and it passed for me.
