More work on wallpapers: animations, lifecycle, scaling, etc. Yet more work on improving the behavior of wallpapers. This fixes a few problems in their lifecycle (corresponding change in the picker also required for this), makes their animations better for hardware that supports alpha fades, adds animations for the wallpapers themselves, eliminates fixed size wallpapers, and adjusts the API for retrieving a wallpaper bitmap to take care of scaling the raw wallpaper image to match the current desired width and height.
