 EIA-608 closed captions are being displayed too long (usually until the
 caption changes).  This isn't usually a big problem except for cases where
 the captioner has explicitly cleared the captions to avoid obscuring some
 on-screen graphic.

 I think this problem was introduced when the OSD was ported to MythUI.  In
 CC608Reader::Update, the captions should be cleared when "subtitle.clr ==
 0 && subtitle.len == 0".  However, SubtitleScreen::DisplayCC608Subtitles
 does not update the display when this happens.

 The attached patch seems to fix the problem.
