[Idead/Request] A Roboport with grid

[Semaphor]

Having a grid in a roboport could be cool. Things you could put into the grid would be:

- More batteries for added recharge power.
- A fusion reactor so that the roboport could be self sufficient without the need for a power grid.
- Some sort of new item that modifies the roboport's construction/logistics range.

I'm not even sure of this mod idea is possible, but it would be cool if it was.
