Mixed layer re-stratification

Code updates:
- Revised mixed-layer re-stratification parameterization (Fox-Kemper et al., 2010)
  to work for general coordinates, albeit with an arbitrary definition of mixed-
  layer depth.
- group updates from Zhi L.
- openMP updates from Zhi L.
- scalar diagnostics from John K.
- diag_table revisions for OM4 (MOM6 and SIS).
- CMORization of some diagnostics (optional) from John K.
- Latest CVmix (no answer change).

No answer changes since dev/master/2014.07.01 .

Significant answer changes:
- CVmix updated to CVMix/CVMix-src@61292f1. This includes a a rewrite of cvmix_kpp_coeffs_low() to mimic the POP order of operations as well as a disabling of enhanced diffusivity at the base of the mixed layer.

Roundoff answer changes:
- Applied bounds to integration limits in remapping.
- Added round-off adjustments in regrid_edge_values.F90 to avoid singular matices for vanishing layers.

Non-answer changing:
- Add z-remapped (lower vertical resolution) output to OM4
- Added more automatic analysis plots

- Added ocean_SIS/OM4_025 (new basis for CM4 ocean component)
- *Major fix for "interp from Z"
- Added z-diagnostics to OM4/MOM6z

This tag is a candidate to go in tikal_201406 patch.

This tag differs from dev/master/2014.01.17 only in using the modified coupler and shared code (post-tikal).

Fixed Arctic salinity bias

* Reduced coupled timestep from 2hrs to 1hr (avoids coupled instabilities)

Other answer changing commits:

* Parabolic shape profile in KPP non-local transport
* Cold-start sea-ice
* Turned off "reproduce_siena" flags
* Bicubic interpolation of winds (rather than bilinear)

Sea-ice initial conditions + turned off BBL-mixing
