Removed legacy code (ListViews) for rendering articles.

The reason for moving away for ListViews is that they are too
simple for our usage. Defining an API which listens for both JSON
and HTML gets too messy using the built-in convenience functions,
so we save code writing our own views. This is also more explicit,
and easier to understand for newcomers to the project.
Wrote a view to serve the events, and deleted the old ListView.

Made the forum link in the navigation link to the facebook group.

Being realistic, we realize we're not going to implement our own forum,
and the treshold for posting in a custom forum here is much higher than
in the facebook group. The Facebook group will now be a dedicated spot
for discussion between our members, while the Facebook page will be our
news channel on Facebook, while the website is our primary resource.
Changed the structure of the event JSON slightly, to ease future changes.

I wrapped the old response in another object, where the events can be found under the
key 'events'. This is so that we might add additional fields later on, like
query metadata or other things we might think off.
Slight changes to the gear JSON API, to make the API consistent.
