anterior_data.pl - Transfer names, passwords, ratings from previous semester
anterior_data.pl -l . -s 001 -o FLA0015 | sponge league.yaml
Copy old name, password, rating (grades) data from the league in league.yaml's 'anterior' field, or (old) 'one' argument, from old 'semester' argument, overwriting new data, in the case of password and rating, only if they don't exist. name is overwritten in the case it's a Chinese rather than English name.
TODO Not touching ratings because grades perhaps broken for old courses, and ratings not being used.
