Add karma, Jasmine, deps and karma.conf.js. Fixes #1291 (#1293)

* Add karma, Jasmine, deps and karma.conf.js. Fixes #1291

* Improved service worker code

* npm start script executes gulp watch task.

* Written a gulp task to compile templates AOT. Get rid of loading deps in unit tests and a preprocessor.

* PhantomJS package is deprecated. Use phantomjs-prebuilt instead.

* Adjust `npm run test`.
