The SMK maps will probably need an update

Also, added a define for GROWNEVERMISSES, which fixes every single jump with Grow but with feels terrible.

- no longer has weirdness with pw_flashing
- can now have an SA1-style effect for it

Just causes a bunch of other, really dumb side-effects, and nothing else I could test suffers from it

Not a solution, but better than the previous.

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.

- Cleaned up some redundant code
- Halved the speed of backwards thrown missiles (previously PROJSPEED/2, now is PROJSPEED/4)

Item distribution debugger is a netvar that enables cheats, so no exploiting!

Scales below 8 players instead of 6 players. The distance multipler in 4P is now x1.14 instead of x1.07.

- different min/max on capped spring pads
- turn the normally almost-useless "non-ramp sector" type into "wall sector", which disables both stepup AND stepdown instead of just stepdown

Fix that thing where item boxes just wouldn't respawn in battle if you nabbed them all too quickly (which is very likely to happen in large netgames where we have the great fortune of playing on battal bowl).

Less grow, less invinc, less ballhog, just a teensy bit less triple orbinaut, and SPB odds no longer scale with lower player counts like other power items do
