	** Fix for bug #352695

	* widgets/table/e-tree-table-adapter.h:
	(e_tree_table_adapter_save_expanded_state_xml),
	(e_tree_table_adapter_load_expanded_state_xml):
	* widgets/table/e-tree-table-adapter.c:
	(e_tree_table_adapter_save_expanded_state_xml),
	(e_tree_table_adapter_save_expanded_state),
	(e_tree_table_adapter_load_expanded_state_xml),
	(e_tree_table_adapter_load_expanded_state):
	* widgets/table/e-tree.h: (e_tree_save_expanded_state_xml),
	(e_tree_load_expanded_state_xml):
	* widgets/table/e-tree.c: (e_tree_save_expanded_state_xml),
	(e_tree_load_expanded_state_xml):
	Be able to store expanded state also in memory, not only on the disk.

	* mail/message-list.c: (struct _MessageListPrivate), (save_tree_state),
	(load_tree_state), (on_model_row_changed), (message_list_init),
	(message_list_construct), (struct _regen_list_msg), (regen_list_done),
	(regen_list_free), (mail_regen_list): Be able to recognize whether
	there has been any change on any row in a list and save expanded
	state only in case there was any change. Also use in-memory storing
	of the expanded state in case we do not want to rewrite full view
	It's for searches only, and it's not stored between sessions.
