restore humidity mass fraction

I propose these changes to Metarelate's metOcean knowledge base. The changes are correct, to the best of my knowledge. I agree to my username being used to label these changes.

i think that relative humidity in % and mass fraction kg kg-1 were altered in error

This all looks fine to me. My mistake in believing Relative Humidity was a fraction, not a percent!
