Add november workshop

[Malwine]

TODO

• add numbers of attendees for last workshop
• rethink displaying all the pictures

[Realtin]

what do you think about adding a link to the blog posts about the workshops?
we have this one about the 2nd edition: http://foundation.travis-ci.org/2016/01/28/clojurebridge/
and this one about the 4th: https://dalzony.github.io/2016/12/clojure-bridge-berlin

[vsmart]

thanks for starting this! 🎉
how about: listing all past workshops, only showing 1 photo (probably the most recent one)

[Malwine]

@vsmart I would even change that to only show the description and picture of the recent workshop and show all other workshops on a second page.

@daveliepmann You have to add a gif when merging 😅
