    [Nereid] construct the player UI when first shown
    
    Defer creating any UI until the window is actually shown for the
    first time. This yields an incredible startup (~2x) startup
    improvement when starting hidden (--hide). We do this in Moblin
    since Banshee is a system service and is started in the session.
    
    This allows all the services to be available, and then the Moblin
    extension adds its panel to the Moblin toolbar.
