Adds AS2 flash.external.ExternalInterface
Removes redundant fields and arguments around handling of dimensions

Specifically, DisplayObject._x, _y, _width and _height are removed, as they're never actually read, but painstakingly kept in sync with they respective values on _currentTransform.

Also, renderDisplayObject only ever uses the given element's _currentTransform, so there's no need to pass that in explicitly.

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.
