This removes Harden from Kakuna and Dragon Rage from Magikarp.
Harden is incompatible with Poison Sting and String Shot, as Kakuna doesn't learn it upon evolving like Metapod.

Magikarp only gets Dragon Rage via a Japanese event, and since international RBY mechanics are used, it's impossible for this to be used.
As far as I know, these are the only incompatibilities.
`BattlePokedex` is now `Pokedex`, `BattleItems` is now `Items`, etc.
I also renamed `Movedex` to `Moves` and `Statuses` to `Conditions`.
`TypeChart` isn't `Types` yet, because unlike the others, it's not
indexed by ID. That should probably be fixed one day.
