Ensure new custom sleep image every time

Browse Source 
When picking a random sleep image from a set of custom images, compare
the randomly chosen index against a cached value in settings. If the
value matches, use the next image (rolling over if it's the last image).
Cache the chosen image index to settings in either case.
