[tor-commits] [nyx/master] Drop set_sort_order()

commit fe0a896f0d805a64ae91de913759967c14bb29b7

    Drop set_sort_order()
    
    Removes our set_sort_order() method. This is a bit of back-peddling in that it
    moves sort_value() back into the Entry, but now that the class is so elegantly
    simple it's a good match.
