More fundamental Jawz changes.

1.) Instead of prioritizing best angle above all else, it averages both distance and angle to figure out which is the best overall target.
2.) Jawz will completely cut out angles higher than 45 degrees, preventing instances where someone behind you is considered a better target than who you're looking at.
3.) Jawz does the 45 degree angle checking in Race as well, meaning that they will ignore racers that are neck & neck with you, even if they're technically the next place above you, so that Jawz doesn't take a hard left into a wall.
