Allow Assembling-Machines to share electricity around/manage wire connections like a small electric pole. You can either build an electric pole on an existing machine, or craft and build directly the electric machine.
The player can now put electric pylons on top of the assembling machines, so the all area around assembling machines can be powered easily.
It's also possible to build at once the assembling machine with its pylon.
