	* message-list.c (get_message_row): new function to do a uid to
	row mapping.
	(mark_msg_seen, select_msg, message_changed,
	message_list_set_folder): Update for Camel flag changes.
	(on_cursor_change_cmd): Rename "row_to_select" to "selected_row",
	and keep a "selected_uid" as well.

	* mail-ops.c (composer_send_cb): Update for Camel flag changes,
	and fix some memory-handling bugs. (Free the post_send_data when
	the composer is destroyed, not when the user clicks "send", which
	could happen never, or more than once.)
	(delete_msg): Update for Camel flag changes, and fix the "holding
	down the delete key skips some messages" bug.
