The existing slack form on the community page doesn't function...
it's trying to post to the community-slack.chef.io site, but the actual
invite form doesn't actually live there but rather in a SlackIn app.
Also, we have some info we'd like new Slack users to receive, such as
etiquette tips and code-of-conduct information.
This change replaces the form with a link to the community-slack.chef.io
site. Also, I fixed a missing space in the surprise code example on
the main page.

The 3.1.0 version of jQuery that we had previously included was
throwing errors; this downgrades to the version of jQuery that
was shipped with the version of Foundation that is in the project.
