refactor(injector): turn scope into a service

- turn scope into a $rootScope service.
- injector is now a starting point for creating angular application.
- added inject() method which wraps jasmine its/beforeEach/afterEach,
  and which allows configuration and injection of services.
- refactor tests to use inject() where possible

BREAK:
- removed angular.scope() method
