Completed the Electrum version handshake, resolved an issue with json-rpc object serialization, implemented base class round-tripping of json-rpc version and message id (keeping it out of the method handlers), added a system level config class for working with serializable 4 part versions. Used the Electrum wallet to fully implement and verify the handshake, with versioning all ready to go for each method.
