* PACMAN generators show network load/supply.
This gives more feedback to players that their PACMAN is properly connected and what the network status is (i.e. you don't have enough generators).
* Buff JRPACMAN to 8 kW.
Shifted all power values up by +3 kW.
They're frequently too weak to power even single rooms so they deserve a buff.
* Change unit format helpers number format.
Always displays one digit of precision. This avoids jumping around when a value is changing live.
