Integrate windmill movement with simulated wind data via WeatherManager

[Josharias]

I want the windmill to change its speed every so often so that it can simulate changing wind conditions.

• At very least, just apply a randomness factor at the beginning of the process now tracked separately in Apply randomness to windmill speed #42
• At most, integrate a weather system complete with air currents based off of ocean and land interactions.

This has been started by @LinusVanElswijk in the WeatherManager module already. It's based on Markov chains that simulate rain and wind and cloud coverage.

I'm working on it every now and then; it would be more interesting if wind had an effect on something 😄

I can integrate the weather system. Having a concrete use case for wind simulation also makes it easier to define a good interface for the WeatherManager too.

While there doesn't seem to be a dependency relation between WeatherManager and ClimateConditions, I'll argue that finishing up what was started in Terasology/ClimateConditions#18 is a somewhat relevant and reasonable prerequisite for this integration anyway. So I'll consider this blocked for the time being.
