New Feature: Control rotation during virtual move

It's now possible to rotate the playspace by turning the controller during a virtual move playspace drag. The feature is activated via a checkbox on the playspace tab. If X Y Z axis lock checkboxes are also checked only rotation will be applied. Offsets will still accumulate as the user swings the playspace around because rotation is now centered at head. This feature is intended for use with manual redirected walking (allowing the user to virtually walk in a straight line while walking circles in physical space). This distance walked is reflected in the X,Z offsets.
