Let players power off Metal Farms

Metal Farms always consume lots of energy. This doesn’t change when they’re idle, which doesn’t make any sense. On top of that, they can’t be switched off. Please make it possible to either switch off Metal Farms when they’re not needed or have them stop consuming energy when idle.

We’d ideal probably want something like control room from BZ, so you can turn everything off how you want.

They should not comsume any enery or very little after they have finished collecting/farming the ore.
