Borrowed the KMessageWidget code to better show passive information.

Borrowed the code from KMessageWidget from Aurelian Gateau, Kdelibs,
to better show passive information and notifications. instead of a
popup blowing in the user's face, a nice, animated and well designed
widget will gracefully fade-in, show the notes, and fade out when
not needed anymore.

Don't add a dive on the globe twice ( well, actually, different dives with same location )
