* signature changing

2001-04-25  Radek Doulik  <rodo@ximian.com>

        * listener.c (impl_event): reflect object data type change

        * e-msg-composer.c (get_sig_file_content): renamed from
        get_signature
        (get_signature_html): new helper function, uses
        get_sig_file_content
        (set_editor_text): removed signature parameters
        (from_changed_cb): new signal handler, sets signature by identity
        change
        (delete_old_signature): new function, deletes old signature from
        the document
        (e_msg_composer_set_sig_file): new method, set's signature
        filename
        (e_msg_composer_mark_text_orig): removed (obsolete)

        * e-msg-composer-hdrs.c: added signal FROM_CHANGED
