Log:

First cut at some restructuring:

* CommDetector2 has the main loop.
* Implement a Canny-based logo detector (which also recognizes when there is no
  logo).
* Implement a blank-frame detector and respect the CommSkipAllBlanks option.
* Implement a very very rudimentary way to combine the two.
* PGMConverter has a #define to control whether to perform true greyscale
  conversion of each frame, or to simply fake up a ffmpeg AVPicture structure
  using the YUV data (latter is the default; it works well enough).

Works against a variety of my recordings. To test:

	update settings set data = '511' where value = 'CommercialSkipMethod';

	[see CommDetector.h]

	or use --method with mythcommflag on the command-line

	There are a few 'DebugLevel' options for each of the FrameAnalyzers.
