WaveSurfing rethink

I tried something like this in DrussGt 2.6.0, and debugged it until about 2.8.0 when I finally gave up on it. I've had some ideas since then that might help, but at least in a wavesurfing-style framework I was never able to get it to work. Maybe it requires looking further ahead than I did (I only did one wave), or maybe more penalty for entering unexplored parameter space, but I never managed to get any benefit from it.

Give it a try though, if you prove me wrong and find some value behind it I might just have to dust off DrussGT ;-)

The really important part imo is to decide when to use this strategy. For LT/CT guns this will definitely help, but for guns with distanceLast10, timeSinceXXX, etc. doing so is rather hard — but when the time before impact with wave allowed us to do so, instead of decel randomly like DrussGT, I think this system could give us a better choice ;)
