background: Inherit Animation from GnomeDesktop.BGSlideShow

Browse Source 
Animation background is just wrapping a native GnomeDesktop BGSlideShow
object, so instead of using composition we can now just inherit from the
native GObject, re-using native properties when possible, and avoiding
to keep an extra wrapper to the bg file.
