Using linked list for current timeline children list
Copy a symbol's transform's properties over to DisplayObject's during initialization

Instead of just assigning the transform to DisplayObject#_currentTransform. Otherwise, instances of a DisplayObject class, share their transforms, so changes to the position of one of them will be reflected in all of them. Which is kinda bad.
