SP bugfixes
@smasson @sparonuz - Hi both, here are my commits. Note that we also found a few bugs in the surface bulk parametrization schemes, but those ones we gave directly to Laurent Brodeau for putting in Aerobulk. I guess those will go into NEMO in the future when Aerobulk is imported again.
I think it would be good to show the SI3 changes to one the sea-ice developers as well but I'm not sure who to ask.
