Fixed WANTED poster drawing over minimap, WANTED cursor being colormapped, and splitscreen position shifting stuff

Fix stupid Orbinaut bullshit

See merge request KartKrew/Kart!120

It actually uses trailing item's throw speeds instead of its own, oddly enough; I don't want to mess with the gameplay there, so I just gave it its own exception.

- Fix Orbinaut/Jawz not accepting top speed changes (This means back-spam being slower now for real works, and the speed buff on boosters for real works.)
- Make the top-speed buffs for boosters not work for back-spam

Let Grow/Shrink revert itself when it changes to 0, as well as add a function for removing either. Means we don't have to modify every single > 0/< 0 check, and is overall cleaner.

Same here

I doubt this hurts anything, but might as well I guess

Beyond a certain threshold, forcefully give 2nd a SPB if one's not already out.

There is a LOT that can go wrong here, so I'm not gonna make this a priority for v1.0.2. If someone else wants to take a crack at maintaining this though, and fixing any and all inconsistencies, then feel free.

Replaces MoveOldExeDlls routine in installer staging

Reason for this is because the SDL2 binaries live in libs/ for ease of copying. The DLLs ought to be in one location.
