Integrate YouTube videos for events

Concept:

1. Videos are recorded professionally and uploaded to YouTube: 
    http://www.youtube.com/channel/UCGQZd1FaRdbZGnOuzh_n9Zg/videos
2. Each event listing will display the videos which have the date recorded set to the date of the event.

Challenges:

1. YouTube does not support the V2 API for Google+ accounts like DCPython
2. YouTube's v3 API to search for videos belonging to a specific user or channel either return errors or no results for DCPython or require user authentication

Approach:

1. Use the videos@dcpython.org account to issue access keys
2. Create a playlist per meetup containing the event date in the title
3. If a playlist is found we'll embed the player
