    SpinButton: Fix an obviously wrong arg description
    
    :climb-rate is not about what you get when you single-click on a button,
    as this implied: it's what happens if you hold down a button or a key.
    Fix the description of @climb_rate to new(), and while here, mention the
    key in the blurb of :climb-rate itself.
