    ui: properly handle "delete-event" signal at Preferences dialog, fixes bug 669384
    
    this bug was resolved once before, here is a short solution description:
    
    the "close" event triggered by the escape key was destroyng the dialog, so
    when an user tries to open the Preferences dialog again what appears is
    an empty/tiny window. Handle the "delete-event" connecting it with hide_on_delete()
    successfully solved the problem.
