Added Delabeler

Is able to remove labels off items that have been labeled. It may be
buggy if items change name also from other things. I think it actually
may be able to restore items that have been written on with a pen, to
their original name. But hey, it's something.

It looks like a card of some sorts. In real life it would be a plastic
card similar to a credit card, which can be sticked below a label and
then used to peel it off.
