Enchanted inventory items continuously recharge their enchantment charges, which getItemPtrFromStore() should account for.
Additionally, prevent framelistener errors caused by PlayerItemUse packets about non-existent items.
Players can no longer unilaterally use items on themselves in their inventory. When they try to use an item, they send a PlayerItemUse packet to the server with the item's details. A serverside script can then check the item and either send the packet back to make the item use go through or drop it.
