Add Release Date + Transcoded/Direct Play to the Roku HUD (down arrow)

http://sdkdocs.roku.com/display/sdkdoc/ifVideoScreen  -- releaseDate is a supported field in the HUD. I have added that and included if the video is Direct Play vs Transcoded. 

I have also appended the EpisodeStr if it exists. Sometime it includes the season # depending on how one entered the episode to play it.
