Myriad of changes!

This is a pretty hefty commit, so let's break it down.
- Fixes Pokedex entries for Bittybat, Bulbasaur, and Shellder.
- ...presumably fixes the options menu.
- Adds a Fishing Group and water wild data to Diglett's Cave, also reduces the encounter rate. More to come.
- Modifies parties, including evolving Rival 2's starter.
- Attempts to fix the Ultra and Safari Balls by making `BallFactor` 4, which appears to be the intended number. Tests yielded positive results.
- Restores a ton of Japanese references that got removed in localisation, including some errors.
