Migrating tablemate_script to use "minusEasties".
Updated the oneoff to be aware that the Easties are removed.
Migrating tablemate_comparisons to "minusEasties".

In this change, I have included the mated_ukvar file generated by the now-migrated ukvar_mated_1226_oneoff.py . So it should all be good.
Migrating autovar_montage_script to use ukvar minusEasties
Migrating to "minusEasties" by adding a location-dependent Case to autovar.

The same "new" criterion is used (in a binary logic way) in a bunch of places, so that it's easy to change. (it's called `case3`)

I have checked to make sure that this doesn't change the number of autovarables that are periodic (it remains at 354, before and after the addition of case3).
