Ship can now produce electricity, dependable on power source (like generator))

Starting to get an idea how to do this the most modularily I can, so in the future it is possible to add modules very easily. I've found that through maps I can link up values with different actors, what each gives and what each takes. 
This update was more about searching for the proper technique. At the end "alternator" module works really nicely, detecs if generator is on, shuts down if it's off, and add power to the ship.
