Update shrinkwrap

Update the shrinkwrap based on the result of:

 1. Removing `node_modules`

 2. Re-installing dependencies with `npm install` using the
    latest npm v3 release (v3.10.10).

 3. Running `npm shrinkwrap --dev`

The changes are a "dev" key added to all dependencies to signify that
they came from "devDependencies" and some additional babel dependencies
that were missed in a previous shrinkwrap update.
