LOTS of things

- Replaces the Old Rod with the Candy Sack, an item to evolve Meltan into Melmetal. Meltan and Melmetal aren't in yet.
- Improves Gym Leader and Elite Four AI by a lot. They still use items, they're just better. Fixes XSpecial use while we're at it; before, it didn't actually increase the stat...
- The Scarlet Book now takes up both shelves, one section for each Paradox Pokemon. I also moved the bookshelf so it looks nicer.
- Text in Celadon University has been reduced significantly, taking up less memory and being a bit more RBY-like. It has also been made more accurate (thanks to Daiginjo for translating my booklet!)
- The Magikarp researcher in Celadon University now gives TM Dragon Rage (no longer unused!)
- Added a guard for Mt. Moon Crater.
- Removed TrainerNamePointers, Blank Leader Name Code, and Dakutens/Hakutens using a guide published by YakiNeen.
- PP no longer uses a shitty graphic and is instead properly implemented into the font, optimising the status screen. Also displays in-battle which is kinda cool.
- Lorelei, Bruno, and Agatha now play the Gym Leader theme, not just Lance.

Still unsure how to fix Celadon University's trainers, all I know is a lot of the information should be taken from the Oak fight I did. The code is radically different and doesn't call trainer headers at all. You'll likely want to start from scratch.

The Mt. Moon Crater Guard's text is a little wonky, not sure what's up there. May have been from the way I accessed Mt. Moon in testing. Anyway, if you want to mess around feel free.
