Changed the order of operations for global sums of arrays.
o this *DOES* change output
- the following results are updated by this change:
exp4 front_relax global_ocean.cs32x15 global_ocean_pressure
ideal_2D_oce internal_wave natl_box plume_on_slope
- changes are primarily due to different cg2d residuals but in some
the Eta field changes and this changes other fields
o the global sum used to accumulate sequentially over all tiles on a single
process and then the result be passed to _GLOBAL_SUM()
o now we create a sum per tile and accumulate the sums
- this should fix differences in sum for two tiles on 1 or 2 processors
- this may help when using more than2 tiles but is not guaranteed
- introducing a gather operation in GLOBAL_SUM() will fix differences
for multiple tiles but only for fixed tiles configurations
- an array based sum function is needed to make this independent of
tile configuration

Added new parameter: deltaTfreesurf
Previously, the free-surface equation was intergrated forward
synchronously with the momentum equations. It is more consistent
to use the tracer time-step. This increases the number of
iterations required but strengthens the damping.
We *SHOULD* make the default time-step equal to the tracer time-step.
However, we don't for backward compatibility. At some point in the
future we need to change the default behaviour.
It turns out that the reason for the "reduced stability" encountered
in large-scale runs seems to be related to excess variability in
the free surface which in turn happens when the waves aren't damped.
Using a longer time-step fixes this.
