[cheese/videobalance: 1/4] Add a videobalance to the pipeline

[Filippo Argiolas <fargiolas src gnome org>]

commit 59dd8ddc966c23f9ada5c69215f91529a3708b4f

    Add a videobalance to the pipeline
    
    Add a videobalance element to video_display_bin to make room for upcoming
    contrast, brightness, etc, preferences.
    Not sure the colorspace converter is really needed, deeper look needed.
