[Babase] ranker again

Thanks!  That's very clear.

Is somebody going to update the rnktypes table with the
addition of new JUF and JUM types, removal of FYM,
and update of the definition queries to reflect the new schema?
(I could do it too, though I am not sure which one of babase_*
databases to update, and I wouldn't want to interfere with any of
the ongoing activities.)

BTW, I looked over the ranking data that's in babase_copy. There
seems to be just three types that have been actually used in the
past: ADF, ALF, and ALM. In particular, both ADF and ALF rankings
were provided for several groups between 1995 and 2005. It
should be possible to check consistency within existing data
using just a SQL query.
