[clutter-gst] video-sink: Add a standalone GStreamer plugin

commit 76d911db3b3e9ac8734b52dc41f83c1e528286a8
Author: Josep Torra <n770galaxy gmail com>
Date:   Wed Sep 21 14:15:11 2011 +0200

    video-sink: Add a standalone GStreamer plugin
    
    * Build the videosink as an independent .so library that can be deployed
      in GStreamer plugin directory.
    * Deprecate clutter_gst_video_sink_new() in favor of the usual GStreamer
      way of instanciating elements
