Forms: keep formes that differ only by ability (Basculin, Toxtricity)

Browse Source 
The cosmetic-form filter now also requires identical abilities before
dropping a variety, so gameplay-relevant look-alike formes (Basculin
Blue/White-Striped, Toxtricity Low Key) are no longer discarded.
274 forms across the snapshot (+10 'other').
