Adds a new accumulator that is powered by consuming batteries. The purpose of this is to allow players to avoid using solar panels to "kick start" a real power system.

When starting ships that have a nuclear / fusion power system, now you can use these battery powered accumulators, pop in a few batteries, get some power to melt ice or start your reactor.

Also on Aquilo, when you need to have a little power to get things started, instead of waiting for a solar panel that doesn't really work, now you have a clear path to generate a little power, to start your steam generation.

The goal of this mod is to allow players who don't like solar panels, to not need them at any point during the game.
