Fall Further World Size and Speed

[Quetz]

I've stopped playing huge maps now. I only play on large. I think I'll stay away from even bigger mapsizes. The MAF issues are enough as-is.

I've stopped playing large, and stick to standard erebus-continent with low sealevel and some worldbuildering to remove peaks and buff AI starts now..

But still get the inevitable crashes/turn delays around 300
