quickbuild.sh argument reg_grid or irreg_grid to select ROMS_rutgers model_mod

[hkershaw-brown]

Description:

ROMS_rutgers regular grid uses much less memory than the irregular grid (NCAR#1090)
However, ROMS has curvilinear and rotated grids. This pull request adds a compile time option (argument to quickbuild.sh)
to select regular or irregular grid.

regular grid model_mod_reg_grid (NCAR#1090)
irregular grid model_mod_irreg_grid (NCAR/DART v11.22)

@mgharamti here is what I am thinking for a ROMS_rutgers (optimized reg-grid for Indonesia or other reg cases), but can switch in irregular grid version. Selection is done a quickbuild.sh time.
