Title: Change the images to transparent to cleanup the black background delta issue

This is to address the problem of the flip clock numbers having a background that can differ in color from the background of the screensaver itself. As a result of this discrepancy, the colors would not match.

This was fairly evident when used on laptops with varying brightness control. Trivial fix was to make the images transparent.
