Map update, engineering

Tired of all these mess ups that have apparently been happening!

I have readded the engineering SMES and fiddled around the wiring to accomdate it. More or less a soft mimic of the previous map. This will allow the engine to be powered by a very specific, specialized SMES battery while the other three power the rest of the station as usual. And only the station.

(I also fiddled with the wiring so that the generator there is actually useable! It needs a knot. It didn't have a knot. Good job, /tg/.)
