Reorganize advanced.yml rank formatting

I know this is a "breaking" change, in the sense that the auto config
updater will wipe old keys and put the default keys back in, but I
think this is a perfect time for that. With the addition of extra
ranks, the old default values don't make much sense with 8 ranks. If
the auto config updater would only add ranks 6 through 8, the values
would be invalid.
