Comment:

 (In [25657]) Added commercial detection speedups.  This works primarily by
 using a scaled
 down version of the recording to detect commercials (1/4 width, 1/4
 height),
 and by doing blank frame detection using less of the frame.

 Preliminary testing has shown that the commercial breaks found are as
 accurate
 if not more accurate with this enabled as with it disabled, with
 occasional
 missed commercials.  This seems no worse than without it, and commercial
 detection is not a simple thing anyways.

 There is a new setting in the TV -> General (Jobs) screen to allow the
 user to
 enable these speedups, and the default is to have the speedups disabled.

 Closes #6824
