Kinect driver for Player

Better late than never right?  I've just committed a driver for the Kinect to the Player SVN, based on the libfreenect library from the openkinect project.  I've actually been sitting on this driver for a while, but it looks like the libfreenect API has finally stabilized enough that publishing a driver is warranted.  Features of the driver include

• On the fly resolution adjustment for both the video and depth images
• On the fly control of downsampling/heatmap display output for the depth image
• Accelerometer and Tilt motor support

Pointcloud and LED support are still absent from the driver, patches welcome!
