Got mouselook working again, albeit with unwanted roll
Got rid of the 'No Oculus' dialog box
Moved stereo rendering into a separate effect class
Turn off hydra init for now because it's causing crashes at launch in hid_init()
Made everything fall back to a single un-distorted view if there's no oculus, and moved mouse handling. left a bug in where the mouse warp after switching apps and coming back causes a jump in direction next time you move the mouse
