Bug 1116: Oculus SDK 0.4.4: Add extra DK1 detection; Add call to ovr_Shutdown() and ovrHmd_Destroy(hmdDesc).

Add extra DK1 detection
  - SDK 0.4.4 w/ DK1 (Linux): ovrHmd_Detect() returns zero!
  - In such case: Try creating one device, which works for DK1 on Linux

Add call to ovr_Shutdown() and ovrHmd_Destroy(hmdDesc).
  - Add StereoDeviceFactory.shutdown() and call
    ovr_Shutdown() for in OVRStereoDeviceFactory.shutdown().

  - Call ovrHmd_Destroy(hmdDesc) in OVRStereoDevice.dispose().
