Fix: Item Stacking

[Darkonig]

There are some items that show stackable in their pictures and in the database that simply do not stack properly in game. I traced this back to an incorrect implementation of the IsStackable method and here is the diff for the fix which replaces the method body that guesses if it is stackable and just returns whether the database record claims it is stackable.
