[MITgcm-support] Prather advection scheme

[Jean-Michel Campin]

Hi,

This has been fixed (on Sun Sept 14), and can now switch to
prather advection scheme (for Temp and/or Salt) and restart
from a simulation which was not using it. Just needs 
 pickupStrictlyMatch=.FALSE.,
(will echo a warning when pickup_somT,S are missing).
