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. However the 0.3.2 SDK also eases the burden on the pixel shader through a distortion mesh technique so it about cancels out. I will do a performance comparison and post it here soon.
