Add Angular 1.2.0-rc.2

This is the whole of Angular 1.2.0-rc.2 as downloaded from angularjs.org
in Zip format, minus the docs/ directory.
Switch to Angular 1.2.0-rc.2

The only major change that needed to be made was that $routeProvider is no

specified in the dependencies of the app (adding 'ngRoute' to the module
dependencies). With that change made, everything seems to work post-upgrade.
