Replace DuckDuckGo example by TodoMVC

[davidbgk]

DDG doesn't seem to have the disambiguation feature (“Zero Click Info box”) anymore. The tutorial has to be updated accordingly.

Thanks for the heads up!

I intend to redo the tutorial based on TodoMVC, as it is a classic among programmers. Any comments, or other ideas? :)

I think it would be more useful to introduce features incrementally:

1. browsing with the *Link magic
2. filling/submitting forms with the setField & submit helpers
3. an end-to-end example
4. tips and best practices

• replace DuckDuckGo by TodoMVC (more stable)
• replace DuckDuckGo - advanced matchers by TodoMVC - advanced matchers (more stable)
• remove CheckMyTrip (doesn't work, too much maintenance)
• remove PDC (live production server, won't scale)
