Adding legacy 1.2 versions of angular-animate, angular-cookies, angular-...

...mocks, angular-resource, angular-route, angular-sanitize, and angular-scenario to address a reference issue when you bring in the 1.2 version of the core angular library. Updated documentation links in the 1.2 versions to point to the 1.2 versions of the documentation. Labeled /angularjs/angular-*.ts as 1.3 in the headers. These will be the starting points for a deeper 1.3 update review - though they are mostly backwards compatible as-is.
