Replace the synthetic "Starter" route with actual in-game locations
(e.g. Professor Oak's Laboratory, Iki Town, Littleroot Town). Starters
now appear at their real locations with method "starter" by remapping
PokeDB's "gift" method during import. Split ruby-sapphire and
black-2-white-2 out of special_encounters aliases since their starter
locations differ from the aliased version groups.
