Adjust ScreenSaverRunner to make the screen saver draw once before sleeping. This fixes the perceived black screen problem with the Message screensaver. Also cleaned up Message slightly to retrieve its string from fortune more cleanly, and readded it to the build since it will no longer deadlock the screensaver module for 30 seconds at a time.
