^Should work already if the type of the item is 18 / ITEM_QUEST.

If you want to change that open char_item.cpp and search for:

if (item->GetType() == ITEM_QUEST)
	quest::CQuestManager::instance().PickupItem (owner->GetPlayerID(), item);

Either you add another type to the if statement or simply remove it.
