Update script.js

Fixes terrain range rings not changing color by altitude

[wiedehopf]

// Color controls for the range outline
let range_outline_color = '#0000DD';
let range_outline_width = 1.7;
let range_outline_colored_by_altitude = false;
let range_outline_dash = null;

See defaults.js please.
As such you need to configure this in config.js and set the appropriate variable to true.

If it wasn't clear, your fix is not a fix but a change in behaviour that does not make sense to me.
