Fixed a crash when building structures in otherwise empty areas.
Improved the map cursor, especially in virtual reality.
Added a 5089-novr.bat launcher that will run the game without virtual reality, even if a headset is detected.
Updated mouse control system in virtual reality; Vive cursor control should be more reliable even if the 5089 window isn't on top.
Disabled ambient occlusion & cartoon effects while in the map, which helps map performance (the effects generally are not seen anyway from a distance).
