Smaller room support

[guysoft]

Hey,
So managed to get VRWorkout loading on my windows machine.
The room setup for level select is just a little too big for my room with the base station setup.
I don't have access to a bigger room, so I scaled down a little the panels location in the Levelselect scene.

I have pushed my changes in to a branch. And wondering if there is a way to add this to mainline - perhaps have an option in the settings for a smaller room and then load the transforms there?

There are the changes that work for me. I will test them a little more, but it lets me push buttons.

Thanks for helping me get this working so far!
