Celeste Hill Gate & other things

- New Celeste Hill Gate location so the entrance into the location makes more sense. Also took the opportunity to include more lore. This replaces Pokemon Tower 4F.
- Fixed a bug that caused the Cat icon to not animate correctly.
- Made the infinite Nugget glitch work properly because I was stupid and didn't test it.
- Luxwan now uses the Small Bird icon to fit with the rest of the line.
- Nidoreign has a new Pokedex entry and classification, centred on the Nido's origins in the Moon Rabbit of Asian mythology.
