Restart estatus on power off

Some times when using Caffeine, I realized that every time when I restart the PC and forgot to disable Caffeine, Caffeine starts in enabled mode, and I think this could be dangerous for security, I usually use caffeine just for some applications and just for a session.
So I added a new feature leaving the decision to the end-user whether automatically disable the Caffeine on power-off.
I forgot to say that English is not actually my mother language, so I apologize if I make some mistakes.
