Extra ocean_time in coordinate attribute for r2dvars for spherical grids

[jprinehimer]

In def_var.F, line 456, the coordinate attribute for r2dvars on spherical grids is set as:

text='lon_rho lat_rho ocean_time'

and then a second 'ocean_time' is appended at line 501 for 3D variables like zeta, bed surface properties, etc. This results in the following coordinate attribute in the netcdf file:

ncdump -h ocean_his.nc | grep zeta

>> double zeta(ocean_time, eta_rho, xi_rho) ;
    ...
>> zeta:coordinates = "lon_rho lat_rho ocean_time ocean_time" ;
    ...

For non-spherical grids the coordinate attribute is set as:

text='x_rho y_rho'

and 'ocean_time' is appended as appropriate.

Yes, I missed that one. Good catch.
