Enhanced Interactive sorter

[JomerDev]

I think it would be very usefull if the interactive sorter could wrap inventories next to it, since this would enable someone to make a wall of barrels with interactive sorters behind it, so one could wrap the barrel and find out how much items are in it

it is already possible, there is a list method on the interactive sorter which returns a list of all the items that are on the supplied side.
