Added DCS atmosphere API functions.

COORDINATE:GetTemperature(height) returns the temperature (optionally as a function of height ASL).
COORDINATE:GetPressure(height) returns the pressure (optionally as a function of height ASL).
COORDINATE:GetWind(height) returns the wind direction and strength (optionally as a function of height ASL).
UTILS.BeaufortScale(speed) returns the Beaufort number and wind description as a function of wind speed.
