	** Fixes bug #218570

	* em-folder-browser.c (emfb_expand_all_threads),
	(emfb_collapse_all_threads), (emfb_set_folder), (emfb_activate):
	Added code to handle expande/collapse all and call e-tree for regen of
	the list.
	* message-list.c (load_tree_expand_all),
	(message_list_set_threaded_expand_all),
	(message_list_set_threaded_collapse_all),
	(message_list_set_expand_all), (regen_list_regened): Added code to
	conditionally check for expand/collapse all and save the state after
	the operation.
	* message-list.h: Added state variable for expand/collapse all of
	threads.
