Added OutOfRangeDataStrategy parameter to Controller Settings

The openvr SDK provides a way to gauge the quality of tracking on a given device via the eTrackingResult enum.

* Drop - Only Running_OK is considered valid, all other eTrackingResults will return invalid poses.
* Freeze - Only Running_OK is considered valid, but other valid TrackingResults will return the last Running_OK pose.
  In esseces this will freeze the puck in place at the last good value.
* None - All valid eTrackingResults will be valid, including OutOfRange and Calibrating results.  This is the default.
