Subject: Properly handle user cancellation for signing/encrypting, just dont
 sign

2002-06-03  Not Zed  <NotZed@Ximian.com>

        * e-msg-composer.c (build_message): Properly handle user
        cancellation for signing/encrypting, just dont sign but create
        anyway.
        (e_msg_composer_get_subject): Wrapper function to get the subject
        from the header object.
        (e_msg_composer_get_to):
        (e_msg_composer_get_cc):
        (e_msg_composer_get_bcc): Same for the destination types.
