New Update 2.2.4.6 with improved VR released

This update includes improvements to the user interface for better VR display. Experimental OpenVR support was added, too.

• The main menu will now be displayed in 3D space in VR mode.
  
• Pressing R will recenter the VR view inside main menu and play mode.
  
• Experimental OpenVR support was added, too. We do not own any HTC Vive, so we cannot test properly. We will fix issues as soon as we get feedback from our users.
  
• The application will automatically detect and use when an Oculus devce is attached using Runtime 1.3. When that is not the case, it will try to detect a device using the OpenVR API.
  
• VR controllers are not supported, yet. Mouse and keyboard are still required for interaction.
