tmp folder has versions of zip files with iceshelf_vbc.F and varinfo.dat modified from original setup

iceshelf_vbc.F updated to allow surface fluxes over open ocean by removing:

!# else
!#  ifndef BULK_FLUXES
!          DO itrc=1,NT(ng)
!             stflx(i,j,itrc)=0.0_r8
!          END DO
!#  endif

varinfo.dat updated to input salt fluxes in units of m/s

Creating a new roms-trunk.tar.gz required updating line 111 of sbuild_roms_NoCice.sh
to read:
tar -xzf ${metroms_base}/static_libs/${roms_ver}.tar.gz

The original used "-xf" b/c the tar.gz wasn't a true gunzip file. I've added back the "z" here.
