[Feature] Artifact power gen and monkey converter

[Mordent]

For the power generator one, I need to look at the powernet code a bit more to understand it, but assuming the general idea is "let you power the station with it" then you probably want to ramp down the output somewhat, as even the lowest one would provide enough to power the whole place for most rounds.

Maybe have it more like 5kW to 500kW generated non-linearly, so something like (pseudocode):

Code:

output = floor (5000 * 1.5 ^ (rand(0,10)))

This puts the output at:

   

This way the higher output ones are rarer. Either way, something needs to happen with the output level, even if it's linear.
