This commit adds the new reject protocol message added to recent versions of the reference implementation. This message is intended to be used in response to messages from a remote peer when it is rejected for some reason such as blocks being rejected due to not conforming to the chain rules, transactions double spending inputs, and version messages sent after they're already sent. This is work toward issue #9.
