libs:
 common.js: Added 'reassemblePayload(payload)' to handle streaming
            packet reassembly as JSON objects.

 socket.js: ping event handler now extracts public key & checksum
            from intial payload.

test:
 test-socket.js: Removed unnecessary intializations for Alice's
                 private/public keypair, initial shared secret,
                 digest, payload encoding etc. Also removed Bob's
                 shared secret, digest etc as these will be
                 created, encoded & verified during testing phases
