Send all three of stdin, stdout, stderr from the client to the server, so that commands can directly make use of them. This means that load-buffer and save-buffer can have "-" as the file to read from stdin or write to stdout. This is a protocol version bump so the tmux server will need to be restarted after upgrade (or an older client used).
