#587 camera1394: corrected documentation, use libdc1394s debayer

[Sebastian Scherer]

This patch changes two things:
- The documentation was wrong about the configuration parameters brightness, exposure, and shutter: It said you should set it to "auto" for automatic mode. This will not work as the above parameters are stored in IntPropertes, i.e. "auto" will not be recognized as a valid value and will be set to 0 instead of PROPERTY_AUTO (defined as -1) as it should. This patch changes the documentation to reflect that the parameters mentioned should be set to -1 for automatic mode.

- camera1394 currently uses its own very simple debayering methods, even though libdc1394 provides a plethora of debayering methods itself: some with much better results. I changed camera1394 to support all of libdc1394 debayering methods.

Can you wrap your new code with #if LIBDC1394_VERSION == 0200? (see other such places in camera1394.cc code); my ImagingSource camera gives all-purple image when I use libdc1394-2.x so I'm still using libdc1394-1.x. So far camera1394 driver code was supposed to support both APIs, your patch breakes that as I can't compile this driver anymore after applying it.

Any progress on getting this patch to work correctly?
