Version 1.04 - Single Controller Play now possible

I have added the ability to play with only one controller. When you pull the trigger, your gun will appear, and when you release it, your paddle will appear. It will use this mode automatically if only one controller is detected. It will switch to two-controller mode when the second controller is turned on. Also fixed a bug where it would have problems using your Vive controllers if you have a gamepad (e.g. xbox controller) plugged in when you start the game. Fixed a few other small things. As always, let me know if you run into any issues. Thanks!
