	** Fix for bug #519292

	* mail/message-list.c: (load_tree_expand_all): Drop function.
	* mail/message-list.c: (regen_list_done): Rather use desired expanded state
	value when creating the tree instead of the default model's value for
	this to have 'expand/collapse all' commands work better and quicker.

	* widgets/tablee-tree.h: (e_tree_load_all_expanded_state):
	* widgets/tablee-tree.c: (e_tree_load_all_expanded_state):
	* widgets/tablee-tree-table-adapter.h:
	(e_tree_table_adapter_load_all_expanded_state):
	* widgets/tablee-tree-table-adapter.c:
	(e_tree_table_adapter_load_all_expanded_state),
	(set_expanded_state_func), (set_collapsed_state_func):
	Drop functions in favor of new functions.
	* widgets/tablee-tree.h: (e_tree_force_expanded_state):
	* widgets/tablee-tree.c: (e_tree_force_expanded_state):
	* widgets/tablee-tree-table-adapter.h: (e_tree_table_adapter_force_expanded_state):
	* widgets/tablee-tree-table-adapter.c: (e_tree_table_adapter_force_expanded_state),
	(struct ETreeTableAdapterPriv), (create_gnode), (etta_init):
	Use either default value of the model to expanded state of new node or
	use the one which has been set (forced) by new functions.
