[Bug] Concealed grids still consume battery power

[LordTylus]

Hello there

I got reports of someone building their jump drive which was recharging for 7 minutes. Went offline therefore grid was concealed. and when he came back online the jumpdrive still wasnt recharged. but instead all the batteries were empty which were full before

So It seems like batteries still consume power while concealned

This is also related to #34

The technical reasons why it happens are in there, not sure about the fix.

Never mind, just a coincidence, there are multiple issues that kind of present a similar way but occur for different reasons.

I think this might be more related to the battery calculation issue that's fixed over here.

Could possibly be something else, but this sounds like it. Thanks again Remaarn for pointing out the real bug in #34
