Title: Add previousStackSize to PlayerUseItemEvent.Finish Close #1379

-Deprecated old constructor and method
-Added new constructor and method with the previous stack size variable as additional parameter

This way, a listener can mirror vanilla behavior and react to a change in stack size when the item finish being used.
