    main: Handle "Powerpoint" buttons on remotes
    
    Some remotes, including the Logitech Presenter R800:
    http://www.logitech.com/en-us/product/professional-presenter-r800-business
    have a number of buttons bound to make it easier to use Powerpoint
    presentations.
    
    We bind some of the buttons used on those presenters to functions
    in Totem to allow starting/stopping playback and seeking.
