(Moving the flag for has_changed from the Hdrs to the Composer itself.

2001-01-25  Jason Leach  <jasonleach@usa.net>

        (Moving the flag for has_changed from the Hdrs to the Composer
	itself. Providing public methods to set/unset a composer as
	changed. Adding attachments now flags the composer as changed)

	* e-msg-composer.c (e_msg_composer_unset_changed): New function.
	  (e_msg_composer_set_changed): New function.

	* e-msg-composer.c (hdrs_changed_cb): Callback to the new signal,
	  uses the new composer_set_changed.
	  (attachment_bar_changed_cb): Add a call to the new _set_changed.

	* e-msg-composer-hdrs.c (class_init): New signal "hdrs_changed" to
	  tell the parent composer that any of the headers have changed.
	  (addressbook_entry_changed): emit the new signal here.
	  (entry_changed): And here.
