Refactored the Rails router to respect properties specified by the model objects. Introduced new support to allow models to modify RESTful object loaders just before they are sent. Sample app completely works. Really fucking happy with how this is turning out!

/**
* Return a serializable representation of this object's properties. This
* serialization will be encoded by the router into a request body and
* sent to the remote service.
*
* A default implementation of paramsForSerialization is provided by the
* RKObject/RKManagedObject base classes, but can be overloaded in the subclass
* for customization. This is useful for including things like transient properties
* in your payloads.
* Invoked just before this Post is sent in an object loader request via
* getObject, postObject, putObject or deleteObject. Here we can manipulate
* the request at will.
*
* The router only has the ability to work with simple dictionaries, so to
* support uploading the attachment we are going to supply our own params
* for the request.
