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.
Perhaps that is how it is supposed to function, but the 3rd person camera was pretty much attached to the players head before, and it didn't really look like it was looking slightly down, though that might be a bug. Now, it is attached to the body direction, so when the player moves his head the camera doesn't swing around wildly. I can raise it up a bit if that is what you prefer.
