Hotfix: PC VR startup

Fixed: with SteamVR (Valve Index and other PC headsets), the game could start in mouse-and-keyboard mode while the headset was also running. The game now waits for SteamVR and starts in VR properly. Changed: the wrist menu now sits a bit further from your hand, so it no longer clips through the tool. Thanks to everyone playtesting and sending feedback! I'm also looking at making menu text easier to read, especially on the main menu. More on that soon.
