** Fixes bug #495123

2007-11-27  Matthew Barnes  <mbarnes@redhat.com>

	** Fixes bug #495123

	* composer/Makefile.am:
	Add a bunch of files for managing composer headers.

	* composer/e-msg-composer.c (build_message), (from_changed_cb),
	(set_editor_signature), (e_msg_composer_set_body),
	(e_msg_composer_get_preferred_account):
	* plugins/exchange-operations/exchange-mail-send-options.c
	(append_to_header):
	Use e_msg_composer_hdrs_get_from_account() to obtain the EAccount.

	* composer/e-msg-composer-hdrs.c:
	* composer/e-msg-composer-hdrs.h:
	Massive refactoring to use new EComposerHeader classes.

	* composer/e-composer-header.c:
	* composer/e-composer-header.h:
	* composer/e-composer-from-header.c:
	* composer/e-composer-from-header.h:
	* composer/e-composer-name-header.c:
	* composer/e-composer-name-header.h:
	* composer/e-composer-post-header.c:
	* composer/e-composer-post-header.h:
	* composer/e-composer-text-header.c:
	* composer/e-composer-text-header.h:
	New GObject classes manage different types of composer headers.
	See bug #495123 for a more detailed description of each class.

	* mail/mail-session.c (mail_session_init):
	Pass the CamelSession to the EAccountComboBox class (ugly hack).

	* widgets/misc/Makefile.am:
	Add e-account-combo-box.[ch].

	* widgets/misc/e-account-combo-box.c:
	* widgets/misc/e-account-combo-box.h:
	New widget renders an EAccountList as a combo box.  Also listens
	for changes to the EAccountList and updates itself accordingly.
