FireControl: one PDeviation shape for the deviation price

Browse source 
DeviationProbability's inline saturate becomes PDeviation(deviation, tolerance), defined
for a zero tolerance as well. No behaviour change for a positive tolerance. Delete-first
step of the evasion term: every later deviation-like price reads this one shape.
