Issue #29: Add subtitle support of Episodes.

Adds the ability to select subtitles for episodes if they are available.
Re-Arranges some layouts to accommodate the subtitle support for the
Recently Aired, On Deck, and Recently Viewed items.
Issue #63: Adjust width for Menu textviews.

Depending on people's descriptions entered for the library in plex,
some items can get trunctated.  We need to make a compromise, and currently
about 20 characters is the max we can support anything more and things
don't work any longer in the text view.
