SkinnableComponent partAdded and partRemoved functions should take in Object not *

Steps to reproduce:
1. Try to override partRemoved or partAdded

Actual Results:
The function declaration has these functions taking in * instead of Object
override protected function partAdded(partName:String, instance:*)
override protected function partRemoved(partName:String, instance:*)

Expected Results:
They should take in object

Workaround (if any):
