Added event JSON API

[evertheylen]

This adds a JSON endpoint to the URL /events/list_json. I'm planning to use this for my own LC to display events on our own website. I've also added some fixes I had to do in order to run the application (in manage.py based on this SO answer and requirements.txt (having two haystack libraries is a bit overkill)).

Happy Easter 😄

The output with demo content installed is (formatted and shortened for readability):

{
  "pending_list": [],
  "over_list": [],
  "active_list": [
    {
      "category": "workshop",
      "organizers": ["Andreas Albrecht", "Sebastian Stanislaw Wozny"],
      "description": "Dear EESTECers,\n\nLC Munich is proud to finally announce its workshop. [....] Be fast, as the deadline is quite soon!",
      "end_date": "2017-04-16",
      "slug": "inktronics",
      "organizing_committee": "Munich",
      "thumbnail": "/media/event_thumbnails/inktronics.jpg",
      "deadline": "2017-04-26T14:05:58.020Z",
      "location": null,
      "scope": "international",
      "start_date": "2017-04-16"
    }
  ]
}

So guys, any update? You've had plenty of time to recover from Congress 😉

Bump :)

The new academic year will start soon in Antwerp, we'd like to integrate this before then.
