Parse (mostly) 2014 schedule and events.

No changes were needed to the daily schedule parser. Only minor changes
were needed to parse the event details.

Note that at this time, there are still a few things that are broken:

- Video URLs aren't parsed correctly.

- event_CE* events aren't parsed correctly.

- Some artists now have SoundCloud links, rather than SXSW-hosted MP3s.
  These are not parsed correctly and will need either a new field or a
  more complicated scraper that hits SoundCloud, but in any case, event
  pages with SoundCloud links don't break, they just don't have a music
  link.
