Add TV-Guide information to live stream plot (#234)

This adds the previous, current and upcoming live show to the live
stream plot.

This also includes a fix where we would show today's TV-Guide, while the
EPG information goes from 6AM until 6AM. So before 6AM we would show the
previous day's EPG.
