kpoppel ee5c6c23fa Changed power distribution method and streamlined the various existing machines.
An electrical network now requires a switching station to work. This statin is the one
resolving the network collecting power and distributing it again.
Added up/down converter. It is kind of finished. It can be updated with a slot for an upgrade
but so far it works without by resolving the types of wires above and below the box.
Tool and machine registering changed to use a table with key+value instead of the iterative method it used to have.
The power radiator changed to be able to send up to 3000MV EUs in a radius of 6.

This update will most likely require existing networks to be dug up and placed again. Also the
switching station must be added.
