master: 6.XX namelist format for input files

    updated : ww3_multi and ww3_prnc updated
    added : ww3_ounf, ww3_ounp, ww3_trnc, ww3_bounc, ww3_shel

    clean up :
    -sort all variable declaration in order
       type / integer / real / double / character / logical
       and for each scalar / array / allocatable

       write all permanent code in uppercase

    update homog feature in ww3_multi.nml to remove NMOVE
    add homogenous field feature for ice

    in aux/bash :
    -set a inp 2 nml converter for each prog
       old T/F format in ww3_shel.inp and ww3_multi.inp
       is not supported by the bash converter inp2nml

    in w3timemd.ftn :
    -add new subroutine to substract 2 time arrays
    -add new subroutine to convert time units to date array

    differences on all regtests :
    -for tp1.8 due to better time precision
    -for netcdf output due to calendar = "standard"
    -all due to namelist logs
