Add AngularJS 1.0.6

Got 'em from

https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.js
https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.min.js

I modified `package.json` to point to `1.0.6`, since odd-numbered minor versions are considered unstable, and I think `package.json` should point to the latest stable. It previously pointed to `1.1.1`. If that's a problem, I'm happy to change it back.
