#3 Patch to support Quick Cam Pro 4000 and YUV12 webcams

[quicky2000]

Hi all,

You can find in attachment a patch to make flashcam 1.4.4 work with Logitech Quick Cam Pro 4000 ( Quick Cam Zoom)
It should also work for all webcam returning YU12 instead of YUYV.
This is quick and dorty patch so I directly override the old value in the init_device method.
A cleaner metho should be to get the pixel format value from the scan_device and to use it into the init_device one instead of using an hardocded value
