Optimize Item Combination Function

[dun1007]

Current function that handles item combo is O(n^3) with recursive call in the loop. Buying multiple items at the same time(i.e EX scroll) can cause a significant frame lag.

Commenting lua code out revealed that the freeze was actually due to engine trying to directly precache all soundclips used by item. So when a player tries to purchase EX scroll by shop UI, it would compile up to 15 sound events at the same time.

Possible fix is adding a separate item that replicates EX scroll, but the compromise will have to be made with UI(no longer displays component, potential lack of clarity for new players).

EDIT: ok nevermind stutter happens for any combine event, just the matter of quantity

Doesn't lag anymore but may be a cause for occasional crash
