- 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
* update $route to reflect new $location
* add some more unit tests to $route
* fix some other failing unit tests
* redirect overrides the url now
Breaks $route custom redirect fn has only 3 params now
