Sets whether only local files can be selected in the
file selector. If local_only is TRUE (the default),
then the selected file are files are guaranteed to be
accessible through the operating systems native file
file system and therefore the application only
needs to worry about the filename functions in
GtkFileChooser, like gtk_file_chooser_get_filename(),
rather than the URI functions like
gtk_file_chooser_get_uri(),
