Fix rotational orientation of pockets. Need to apply same fix to ProfileFaces. Fix final depth issue based upon error in rotational orientation fixed here. Add property, `LimitDepthToFace` to facilitate easier pockets and face profiling on rotational-enabled operations. Hide rotational support properties when operations do not use rotation. Remove unnecessary property, `B_AxisErrorOverride`, and delete dead code that used it.
