Oculus SDK Upgrade

This Oculus SDK is now 0.3.2. You can download the new SDK at https://developer.oculusvr.com/?status=1

Notable changes in this PR:
* Timeshift for better prediction
* Chromatic aberration correction
* Higher resolution for the OR. (We were using low res this entire time :P )
* Proper mirror mode and third person for Oculus that doesn't make you sick. Mirror is cool.
* Space bar will attempt to reconnect to the rift, so you don't have to restart interface anymore.

Since we are now rendering at higher res, the performance may be a bit lower. Here is a side by side comparison: http://imgur.com/PJSi8lG

Note: Glow effect significantly harms FPS in the oculus because it requires large intermediate textures. You can now disable glow effect in the Developer/Rendering Options menu.
This seems odd to me. When I'm looking in the mirror, and I tilt my head toward my right shoulder, you're going to make it look like I tilted my head toward my left shoulder? I can see how for a symmetrical avatar, that would closely simulate a mirror, but it's not actually what a mirror does. 

I understand our "mirror mode" is not really a mirror, but this doesn't really fix it. Besides, if it really was correct, why wouldn't we do it for all modes, not just oculus mode?
