CPlayerState

built out the second PlayerState request object: AdminGrantRequest. Added CPlayerState and started work on the client side of the transaction pipeline. 

I'm thinking about how best to build a request/response pattern on top of the networking layer I wrote. That layer is entirely object based (just streams of objects in each direction). I think I'd like to keep it that dumb, and have ClientRequest /ServerResponse objects that contain the necessary state to provide callbacks for specific requests on the client.
