Bigger bypasses of control routines when the control has been
overridden
Individual config files for turbines and reactors. Persistent between
reboots, remembers your last saved settings.
Cruise mode override bypass
Changing flow rate no longer toggles flow rate override on and off.
Changing the flow rate clearly indicates intent, so we put the override
flag on and leave it there.
Changed the rate at which the regular algorithm adjusts reactor rod
control rates. Instead of being 1:1 we now move at 1:5 speed because
there is a wide loophole where big adjustments can cause a swinging
pendulum effect continually missing the target.
