[evolution-patches] fix for message-browser

[Jeffrey Stedfast <fejj ximian com>]

keep track of the signal handlers by id, fixes at least a warning. For
message_list_built's callback, might fix an actual bug as well.

+	Might fix bug #45368 but I wouldn't bet on it.
+
+	* message-browser.c (message_browser_new): Record the signal id
+	for folder_loaded.
+	(message_browser_folder_loaded): disconnect by id rather than
+	searching for the handler. Save the id of the message_list_built
+	signal handler.
+	(message_browser_message_list_built): Disconnect the handler by
+	id.
+	(message_browser_destroy): Disconnect the signal handlers by id.

 	* message-list.c (on_selection_changed_cmd): Save the idle_id
