Title: removed redundant extend

Inside the Backbone `extend` function:

``` javascript
child.extend = this.extend;
```

replicates functionality from the Backbone `inherits` function which calls:

``` javascript
_.extend(child, parent);
```

Is this intentional? If so, could you please explain why it is necessary?
