Title: Small electric engine, small 1 cylinder 2-stroke engine, little metal tank

Everything started from https://github.com/CleverRaven/Cataclysm-DDA/issues/9140.
Added some cable to motors byproduct.
Also doubled the weight of tanks.
TODO?: deconstruction of the rest electric engines and recipe for one or two gas engines.
