Title: Added toJSON method

The reason for this is that `Marionette.ItemView`'s `serializeData` falls back on `this.collection.toJSON` if a model cannot be found in the instance, as you can see [here](https://github.com/marionettejs/backbone.marionette/blob/master/lib/backbone.marionette.js#L1404).

Tell me what you think!
