F/deserializers

Deserializes data passed to the CakePHP layer via an HTTP request.

Uses a custom DispatchFilter to process the json payload data and deserialize the records (into CakePHP standard data arrays) and set it to the `$this->request->data` property of the Controller.

In essence with this in place your controllers can deal and process with normal data as you would expect.
Don't use _ for properties. It is already protected.
