    Reset title when an empty title string is given
    
    With this patch, st will reset its window title when an empty string is
    given as the terminal title. For example:
            printf "\033]0;\007"
    
    Some applications, like termdown, expect this functionality. xterm
    implements it, but it seems that most other terminal emulators don't.
    In any case, I don't see why there should ever be a case where the st
    window doesn't have a title property.
