    GtkFileChooser: don't override already opened folder
    
    When filechooer is re-used (instead of being created and destroyed
    every time it's needed), it might happen that the directory the
    application wishes to initially show is the same directory that
    was shown last time the filechooser was used. In that case, make sure
    filechooser knows that it does not need to do its default "select $pwd
    or $home" routine.
