0.2.0 rebalance & fuel-rod heat penalty

Rebalancing generation numbers based on RF conversion.
Heat now further reduces power production by inhibiting spontaneous
fission, as originally intended. Production goes down to 20% of nominal
by 5000C.
Fixing a bug that was draining too much power from the reactor if you
had powerProductionMultiplier set to something other than 1.
More 0.2.0 rebalancing

1-block reactors now "competitive" with base TE3 dynamos
Shouldn't affect high-end reactors too much
