Changed the craft of energy & liquid transmitters

It's just a proof of concept.
The problem was that it was needed to use TWO atomic cores to upgrade ONE transmitter to the Ultimate tier...
I made it possible by placing 7 (so 6 more) transmitters with the two upgrading items.
So I changed the number of crafted basic transmitters to 7 to make it more logical & appropriate

If you don't want to keep these numbers, I can manage to do another commit corresponding to what you prefer :)
