Remove items from inventory by instance id

[janisgitendorfs]

Please add option to remove items by their instance id.

Case example:

As a developer I would like to create a system where one item can be selected for upgrade and other items can be selected as items that will benefit the item to upgrade. Each item has value X defined in numeric properties. Upon successful action the list of selected items are deleted from player inventory and the value X (defined in numeric or string properties) are incremented by the calculated amount from selected items.
