Soline Bielli : 01/03/2019: Sea salt update: the significant sea wave height now influences salt emission.
The sea salt is either set to a default value of 2meters or read in ECMWF Grib file (if the variable exists).
Now 5 modes are available (3 before) and the order in output is changed.
The large-scale sea wave height from ECMWF grib is 2D. HALO2 update of the ls variable in modeln is not yet adapted to 2D field (it is switch off in this version for this variable).

* use new file structure for CLUOUT and CLUOUT0 (->TLUOUT and TLUOUT0)
* use PRINT_MSG with NVERB_FATAL to replace (some) "callabortstop"
* set TFILE_OUTPUTLISTING  to select file for outputs of PRINT_MSG
* removed some unused code

+ removed unused variables

Philippe 11/04/2017: IO: use IO_WRITE_FIELD (and others) for several fields (chosen from testcase 014_LIMA)

+ use IO_WRITE_FIELD for several fields (chosen form testcase 011_KW78CHEM)

 + use IO_WRITE_FIELD for several fields (chosen form testcase 009_ICARTT)

* added several LB fields to TFIELDLIST
* added several fields to TFIELDLIST
* added scalar integer fields to TFIELDLIST and possibility to write them

* added ALLOC_FIELD_SCALARS subroutine
* modified arguments of WRITE_LB_n
