Changeset 9943 for NEMO/trunk/cfgs

Message:

add a proper correction for negative values occuring after Ultimate-Macho advection scheme. This correction conserves mass, heat etc. 3 diagnostics have also been added in the outputs to make sure that the negative values are indeed small and unimportant in view of the advantages in using Ultimate-Macho
