This also fixes an absolute TON of errors with evolved Pokémon learning
a move both at level 1 and the pre-evolution's level, as well as
miscellaneous other problems.
Only the version group a forme actually exists in now has any moves for
that forme.
In addition, Deoxys formes were not showing any gen 3 moves at all
previously, because they were marked as only existing in gen 4. This
has been fixed.
This gives the correct ordering to level-up moves that have the same
level.
It also fixes move errors with Wartortle, Blastoise, Persian, Golduck,
Rapidash, Kabutops, Croconaw, Feraligatr, Noctowl, Sharpedo, Piplup's
family, Shinx's family, and Yanmega. Yikes.
