Regional Trades!

- Regional trades now dummy out the "-A" thing etc so they look nice
- Added Celadon, Saffron, Viridian, and Vermillion regional trades
- Added Galarian Sidegrade trades to the S. S. Anne, but Perrserker and Sirfetch'd specifically don't work. I have zero clue why, as they work the same as the rest.
- Corrected grammar in the "Happy" text when you finish a trade
