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.
Mirror mode still works just fine. The extra code here was unnecessary. All we have to do is get the average eye position, set the camera distance to the mirror distance, and flip it around.
