Change the router to ui-router to better fit with hybrid app development

[archive-a1]

The Ionic Framework, which is targeting Hybrid App development, is using ui-router and not ngRoute. It would be helpful if the seed was updated with this router, since it will fit the needs better of Ionic users. Ionic + Angularfire = SUPER.

So example, instead of $routeProvider, use $stateProvider and $urlRouterProvider. See also these Stackoverflow threads:

This is not an ionic seed. While I recognize the usefulness of this idea, the angular-seed utilizes ngRoute and we'll follow suit until that is changed as well.
