fpsVR - 1.16

The fpsVR has been updated with the following changes:

• Update to OpenVR SDK 1.12.5 (was 1.11.11)

• The "Desktop Utilities" overlay coordinates are now calculated by using the position of the headset at the moment the dashboard is opened (and not by position of the Valve desktop overlay). This should solve some issues, both existing and possible in the future (in case Valve makes any adjustments to its overlays).
