Rename Super Jump as Superjump

Selicre suggested this, and after some thinking on it, I think they're right. This is also how the wiki spells it, though they have the J capitalized half the time. I kept the tech name with a capital J, for readability, but maybe we should make it always capital instead, I'm not sure.

We use canWalljump and canCarefulJump meaning that a kind of jump uses lowercase j with fullname Walljump wheras descriptor jump keeps the jumping word as Jump and Superjump would be a kind of jump which is different from InsaneJump.
I would say strat names should match the tech name so I'd rename it to canSuperjump.
But I prefer canWallJump and maybe still miscase it regularly. I also see canTurnaroundSpinJump and canFlatleyJump and canGravityJump are big J, so WallJump is the only odd one.

I have also disliked canWalljump being a lowercase j. I'll fix it in another PR.

My thoughts were pretty freeform there, but now Superjump is the only odd one with a lowercase j.

I think that's how it should be. Superjump would basically be one word and wall jump would be two.
