Add a delineation in start-up section for run once

[Nergal]

While investigating two command prompt entries that both had not been there previously, so opened in registry in ccleaner triple dot (like you should always do for new unclear entries instead of blindly turning everything off) and found them in the run once hive, so I restarted and they were gone in ccleaner. So I thought, since they announce themselves as run once, rather than them not listing at all to delineate them as these are run once and should self remove at reboot.
