Refactoring pass one

Cleaned up some variables being passed to monitors.
Redid the main reactor temperature adjustment algorithm using heat
differentials to spike the control rods whichever way is needed.
Objective is to get the reactor into cruise mode quicker.
Forgot the case of cold but not increasing or decreasing.

Same algorithm as for cooling.
