Small tweaks to make getting started w/ angular even easier

- Updated vagrant to sync the angular folder to the host machine
- Updated vagrant to forward the ports used by grunt
- Updated puppet to include compass and the angular generator
- Added a little script that modifies the grunt file so the host machine can connect to it.
- Updated puppet to install compass and generator-angular.
I think this should be http://localhost:9000 since you already added a port forward.
