Added a few tweaks to make it even easier to get started with angular.

- Updated vagrant to sync the angular folder to the host machine
- Updated vagrant to forward the ports used by grunt
- 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.

Merge pull request #1 from dberringer/master

Use angular generator by default instead of webapp. Also improved handling with port forwarding, sync additional source folder, moved manual shell command to bash script.
