NEMO release nemo_v_3_3_1

The new release of NEMO nemo_v3_3_1 is now available
Practical details available here: http://www.nemo-ocean.eu/Using-NEMO/User-Guides/Basics/NEMO-Quick-Start-Guide
As mentioned in previous 3_3 announcement, this version corresponds to 3_3 code with dynamic allocation added. Here are the main implications:
- number of processors are now part of the namelist nam_mpp
- for your own configurations, definition of the parameters in par_*h90 have to be slightly changed (see for instance par_ORCA_R2.h90)
- for developers, the coding rules have been updated

In addition, a minimalistic number of fixes relative to 3_3 have been added:
- surface condition in trazdf_imp.F90 ( in use when ln_trazdf_exp = .FALSE)
- time splitting with BDY (in use with key_bdy and key_dynspg_ts)
All future developments will be based on version 3_3_1, so if you plan to move on a 3_3 version, 3_3_1 is highly recommended.
