[libfreenect] add driver library for the MS Kinect.

libfreenect/DESCR

+Horribly hacky first take at a Kinect Camera driver. Does RGB and
+Depth.
+
+main.cq implements a simple OpenGL visualization. Hopefully it should
+be mostly self-explanatory... You pretty much just open the USB
+device, call cams_init(dev, depthimg, rgbimg), and your depthimg and
+rgbimg callbacks get called as libusb processes events.
+
+TODO:
+        - TONS of cleanup. I mean LOTS.
+        - Determine exactly what the inits do
+        - Bayer to RGB conversion that doesn't suck
+        - Integrate support for the servo and accelerometer 
+	  (which have already been reverse engineered)
+
+BIG TODO: audio. The audio chip (the Marvell) requires firmware and
+more init and does a TON of stuff including the crypto authentication
+to prove that it is an original Kinect and not a clone. Who knows what
+this thing does to the incoming audio. This should be interesting to
+look at.
