Cleaned up the generation script, fixing the doc-blocks above the client actions.

Replaced the transport, giving it all of the functionality that was brought over to the client and making the client simply a place for the API to live. Essentially a shell that can easily be removed.

spec'd out the TransportRequest which will eventually inherit from one of server possible promise implementations and will be plugable. It will also implement the "abort" functionality needed in an environment like node.js
