Title: Return statements on delegateEvents

Don't know if there was a reason to not have a `return this;` in `delegateEvents`, but I finding this situation coming up a lot, where i wish it chained:

```
this.$el.append(this.delegateEvents().render().$el);
```

Then I added a return to `undelegateEvents` as well for consistency.
