Candy Jar finished

- Fixed a bug where the Candy Jar would load `wIsInBattle`'s 01, causing it to zero itself out every time.
- Fixed a bug where the Candy Jar would display `wMysteryBoxActive` due to the way `text_bcd` was being used. Replaced with `text_decimal` so it actually displays properly as well. No hex!!
- Added a test function for the evolution in the debug party because that's cool
