Change the handshake pattern to XXpsk0. #18

This will allow implementations to use the same keypair they use for signing posts in the Wire Protocol for authenticating connections in the Handshake Protocol.

This looks good to me. I really like that the change provides us with an authentication mechanism during the handshake.

Are there any downsides to this addition that you're aware of?

Only that it requires another transmission step.

NN:
  -> e
  <- e, ee

XX:
  -> e
  <- e, ee, s, es
  -> s, se

Cool, thanks for the clarification. Seems like a perfectly reasonable tradeoff to me.
