Unification of temporary item IDs

Hello! Rejoice, for it is I, the eye watching over everything.

This one is a simple ( in theory ) one. Let's bring the items with the same name ( the same item ) under the cover of the same item ID so that they stack.

Prime example: Smoke helmet 300 days + 30 days + 70 days. You're wasting 100 days of smoke helmet for nothing even though you have rightfully earned all of those. You bought the 300 days for zp, you won the 30 days from crates and you bought the 70 days for coupons on the hopes it might end up on top of your 300 days. WRONG.

In any case, idea is simple - stack temporary items together.

That is all.
