change the graphic for either copper wire or copper cable

[joshinils]

currently both use the same sprite.

I tried to set up a chest limit, searched for copper, clicked the first thing, but the condition didn't work.

It would be more obvious if the copper wire has a different symbol than copper cable.

simply to avoid this confusion

I had the same issue when setting a splitter filter. Took me a while to figure out why it wasn’t working (I had set it for copper cable, not copper wire).

Does it even make sense to allow the cables to be set as item filters?
