    Enable PolyKinds for Control.Category.
    
    This change will allow us to make various new things instances of
    Category, such as promoted tuples.
    
    Original discussion from libraries at haskell.org:
    
      http://www.haskell.org/pipermail/libraries/2012-August/018268.html
    
    Fell off the radar. No complaints in the 2 week period since being
    brought up again:
