    Hack the row spacing of a single-row table
    
    The table for the Time preferences in the calendar's General preferences page,
    when Evo runs in Express mode, has only a single row of visible widgets;
    all the other rows are hidden in Express mode.  However, GTK+ 2.20 and earlier
    will include row spacings even for empty rows in GtkTable (or those that only
    have invisible widgets).  Since that table has only a single visible row
    in Express mode, we hack its row spacing to be 0 so that we don't get any
    extra spacing in that case.
