Add jekyll meetup integration

[jjhale]

Could add it using the Meetup api like this (using client side JS to make a request).
civictechdc/codefordc.github.com#217

Or could have a script that pulls the data from meetup and then pushes the data to GH.
Like https://github.com/sfbrigade/codeforsanfrancisco.org/blob/gh-pages/scripts/update-meetup

• we'd need a server to do this automagically,
• Could have cron on someone's laptop run it.
  -or we could rely on the person who updated meetup to do it?

Could have a cron job on Google app engine that

• polls meetup and generates the yaml form the site
• pulls the yaml file from GH ( https://developer.github.com/v3/repos/contents/#get-contents )
• compares the files
• updates file on github if required ( https://developer.github.com/v3/repos/contents/#update-a-file )
