  * This class represents item that player has. It has no information about item feature, just it's handle in database. To get information about item type and it's features you have to use {@link OTS_ItemType OTS_ItemType class} - you can get it's object by calling {@link OTS_Item::getItemType() getItemType() method}, however you need to have global item types list loaded.
