    GStreamerSharp: Rework initialization to match the native backend
    
    The native C GStreamer backend builds the pipeline during the "delayed
    initialization" phase, which allows other extensions to be notified when
    it is done. So we move the corresponding part from the Gst# PlayerEngine
    constructor to the Initialize method.
    
    This fixes the "Equalizer" menu item to be enabled when an equalizer is
    available, and maybe some other things.
