Describe the Suggestion

For now windmill bearing behaves like this:

Which is fine but it breaks turnable windmills - the fans spins in opposite direction and in some builds it looks weird.
My suggestion is to keep that behavior by default(since some builds may depend on that behavior) but add option for bearing that makes it's rotation axis direction relative to the direction the bearing is facing like in case of creative motor.
I don't know if that has been suggested before or not, the quick search haven't given any results so I apologize in advance for making duplicate.

+1 To give an example of a build where this issue is relevant, I'm currently working on a create-only flying machine with the ability to rotate to change direction. This windmill behavior is very inconsistent and difficult to predict, and I don't imagine that it's intentional. This issue seems more like a bug report than a suggestion.
