    Use sd to control difficulty of most CECP engines
    
    I was disappointed when I discovered that most engines did not respect
    the depth command.  But it turns out that this is a GNUChess (and
    Phalanx)-specific extension.  Everyone else uses sd for the same
    purpose. This means that we get to provide meaningful difficulties for
    these engines after all. Yay!
