More (very small) AI improvements

- Fixed a bug where the Elite 4 wouldn't use Full Restores. Apparently the game only allows one item per trainer.

- Gave Oak and Chief custom AI found from proto assets (then changed to be less ass)

- Small amount of balancing

- Minor text fixes

- Figured out roughly how the current high-level AI works (Stat boosting moves are only used sometimes on the first turn, Recover is only used sometimes when below half health, otherwise just attack with a move that isn't ineffective. More testing needed for stat lowering moves and things like Barrier)
