Update: visible wind, high scores, visual improvements.

Visible wind wisps to help you see where the wind is coming from.

Trees now sway in the direction of the wind (and they're taller too).

Persistent high scores per fire in both the demo and full game.

Subtitles now default to on, you can turn them off on the main menu.

Heli rotors now spin.

High loads on planes cause wingtip condensation trails.
