Apply 1895318, with some cleanup.

This patch implements dploog's suggestion of hysteresis on piety.
gain/lose_piety() adjust you.piety_hysteresis first; you.piety is
modified with the leftovers (if any) once the hysteresis reaches its
limit.

Players start out at the upper end of the hysteresis region, meaning
there is no lag on piety increase, but a lag on piety decrease.

Hysteresis value set by "#define PIETY_HYSTERESIS_LIMIT 1"

Does not break old saves.
