Show upcoming event using the Meetup API

[HipsterBrown]

We would like to keep the site up to date with the latest event info without needing to hardcode it into the site every month. Luckily, there is the Nodebot.nyc Meetup page and a Meetup API to get our event info.

@reconbot mentioned having two tracks of events for Nodebots.nyc. We can prefix the title of each event, i.e. "[Workshop] Title of the Next Nodebots Workshop", to inform which track is up next.

Needed Info:

• Date of Meetup
• Title of Event
• RSVP count (?)
• Link to event page

Should be able to get all that from the /groups endpoint/
