bugfix: KCM config panel not showing up (#198)

    KCM complained when trying to open up the script config panel:

        Plugin does not provide configuration file in expected location

    This was due to a behavior change in KWin when loading KCM modules for
    plugins. We need to designate the related KCM module manually, using
    `X-KDE-ConfigModule` field in metadata

    Note that we're using `genericscripted` module, which generates config
    dialog using `config.xml` and `config.ui`.
