[mythtv] Commercial flagging during record (was "tv_grab_uk graphical setup")

Great job Chris.

One question... Does this remove the restriction of hitting the Z key within
2 seconds of a commercial now?  Seems like it should be able to.  Now, if
you hit Z anywhere within a commercial timeframe, it should just skip to the
end and resume playback, right?  We often find ourselves missing that 2
second window on the first shot.
