sanikoyes 64f77aa8f3 1.Change interpolate_callback:p_times_in_sec argument before p_callback argument(more readable)
2.NodePath replace to instance_ID(can control object doe's not in scene tree)
3.Change interpolate types from Node to Object, can control more types(etc script class object)
4.Add pending_update counter, avoid insert/remove interpolates-list while traversal it
