Make batteries be able to removed by click dragging battery container into offhand

[Ikea]

could be a neat change but would allow farming of batteries from mechscanned items

Already a thing, just a bit more of a pain in the ass to do now. Get a bunch of ectoplasm from spooky dans, make some cheap batteries, and swap them out using those. Would not be opposed to mechscanned items coming without a battery, and batteries being scannable seperately. Would make it harder to mass produce things like phasers and tasers as a result of this change, but I am not opposed to that.
