    loginManager: Kill ConsoleKit support
    
    The code path is completely unmaintained and untested (and probably
    unused as well, considering that nobody has complained about accessing
    the session object's Active property which does not exist in the
    ConsoleKit case).
    Most of our ConsoleKit code is already a dummy anyway, just do the
    same for the remaining functionality.
