fix directive test because of newly used $templateCache

big round-up

- split `gulpfile.js` in configurations and tasks, located under `build/`
- load directive templates by `$templateCache` instead of `templateUrl`
- rename markers in `index.html` from `bower` to `vendor`
- fixed wrong npm script `prestart-webdriver`
- production server now listens on port `1338` beside development server on `1337`
- moved all unit test to folder `tests/unit/`, all e2e tests still be in `test/e2e/`
- use `$location` provider in `app/examples/controller/controller.controller.js` to get actual location instead of being static
- rename `app/core/navController.js` to `app/core/core.nav.controller.js` to be consistent
- updated dependencies
- added documentation to all app files

add test dependency to bower.json
