Touch controller models in SteamVR

The latest SteamVR Beta has added Oculus Touch controller models. So now people with Touch will see the proper controller when using SteamVR. I'll be adding support for this in Chunky Orbits soon. Until then, things will look a little funny if you are on the SteamVR Beta and using Touch. The default button mappings have also changed in the beta. Menu buttons are now B and Y, and the System button is now the Left Oculus button. These new mappings should make their way to the normal SteamVR client soon. You might temporarily see some incorrect button labels depending on which version of the client you are running.
