Merge branch 'master' of https://github.com/marsam/Mining-the-Social-Web-2nd-Edition

This merge is a substantial change and fundamentally changes the way that Vagrant works.
It provides configuration management for the Vagrant box with chef instead of with a
Bash script (bootstrap.sh.). In addition to Chef providing better configuration management,
it also configures the box nearly 3x as fast. The new time to configure the box should be
around 10-15 minutes as opposed to 40-45 minutes.

Thanks so much to @marsam for this awesome pull request!
