Changed to use mail_save_part to save the data in another thread.

2001-01-28  Not Zed  <NotZed@Ximian.com>

        * mail-display.c (write_data_to_file): Changed to use
        mail_save_part to save the data in another thread.
        (save_data_cb): Hide the fileselector once we have a button press,
        and are saving stuff.

        * mail-ops.c (mail_save_part): New function to save a part content
        asynchronously.
