Code effeciency project: Sun datum

Because of the wrong direction of this sign, every single solar array was being checked for occlusion every tick.

This should fix that right up.

Trackers set to update their angle only when the sun does.

Solar panels set to calculate occlusion every minute (was every tick (though thought to be set to every 6 minutes (36 degrees)), now checks every 6 degrees of sun movement or so)
