Previously, there were a staggering number of 14 different physics lists; Many were virtually identical to others, with the only difference being Knuckles' jump heights.
It makes much more sense to store Jump Heights separately.
The total number of lists is now down to 8; 4 above water, 4 for below, and all of them are meaningfully different.
This also serves to simplify adding new characters.
