Use Crafty's xboard protocol layer for communication:
Since recent >19.x crafty, there is something strange going on with
display nogeneral.  Another bug which appears sometimes is that
crafty (in its own mode of displaying stuff) echos the oponent
move (our move) which raises an error (obviously).
xboard mode is really a lot easier to parse, and I even managed
to keep the 'evaluate event without any problems.
