Power as a logistic ressource

[Sokyra]

I would be great if we could use the accumulated power as a constant like we can do with all the other items.

We could then setup things to run only if there is at least 1GJ stored...

This has been planned for a while. It was supposed to be in 0.12, but parts of the circuit network rewrite got pushed back due to time constraints. I would look for accumulators accepting red/green wire in 0.13.
