[Therion] Change altitude colours

[Paul Rowe]

Excellent! That's two new things I didn't know how to do. I like the

I have only altered the colours slightly, including adding in some
additional bands. I can see the smoothed colours still works when there's a
lookup table for the altitude colours:
