Describe the bug

As in the title (originally reported by a user on openrocket-bugs mailing list)

To Reproduce

1. Open "simple model rocket" example
2. Select a simulation
3. Click "Edit simulation"
4. Set "Average windspeed" to 0
5. Do not change standard deviation
6. Close with "OK"
7. Run simulation

Simulation gets an internal exception.

What platform are you running on?

Linux

Additional context

The issue was masked if the st dev was changed, as setWindSpeedDeviation() in SimulationOptions checks the wind speed and ensures it is at least 0.1. The UI is not updated to reflect this(!). You can manually set the wind speed to 0, and as long as you don't update the standard deviation it stays as set.

1. Note that a wind speed of 0 can't have a st dev other than 0
2. We appear to be using a pink noise generator for our wind model. Looking briefly at wind speed distributions, we should probably be using something else (and I'd never heard of the ones I'm seeing -- Weibull seems to be popular?)
