Better emergency generator?

[rulib]

The experimental local generator is pretty horrible as-is, it burns most of a plasma tank to just partly charge a power cell and all it does is charge cells. I suggest that it be replaced with one that can burn things like a furnace and powers the local APC. Also keep the ability to run off a plasma tank intact if you happen to have some around, and give it a power cell charging slot. Basically make it a hybrid of how it is now and a furnace that magically powers APCs. It is balanced by its high cost and the fact that none exist on the station at start, to my knowledge.
