    configure: disable ConsoleKit support by default
    
    This commit requires users to explicitly --with-console-kit
    
    It also adds a message pointing out ConsoleKit is deprecated and
    links to a wiki page with more information. See:
    
    https://mail.gnome.org/archives/desktop-devel-list/2015-January/msg00108.html
    
    for discussion. A future commit will remove ConsoleKit support entirely.
