Fixes Mantis #3255. Thank you kindly, MCortez, for a patch that:

Changes to IWindModule interface: Change from assuming a single array of 
256 Vector2 values to a lookup function that takes region x, y, z and returns a Vector3
* Changed llWind() to use new lookup method of IWindModule
* Moved logic for determining the wind at a given point in the data array from 
llWind() to the Wind Module itself.
