Rework CeladonU Trainers

This refactors the Celadon University trainers to ensure that they process properly without the odd memory leak-y thing I did before. Overall works the same, just works for the intended purpose.

I also applied what I learned to Professor Oak, giving a Yes/No prompt and adding some pre-battle music as I originally intended.
