[Simon Feltman <sfeltman src gnome org>]

commit 9b02b29016958791dfa9d7ebfc6c2ec44ab5690d

    overrides: Fix __repr__ for various Gdk structs
    
    Change __repr__ overrides for Gdk.Color, Gdk.RGBA, and Gdk.Atom to return a
    string reprentation that is valid Python given an expected environment.
    See: http://docs.python.org/2/reference/datamodel.html#object.__repr__
