migrate to components & component-router

[maybeec]

Angular 1.5 introduces the component concept, which has been backported from the current angular2 development. The notion of modules will be restricted to the fact, that in angular2 each file has to specify exactly one module. Thus, the representation of business components has to be re-thought as modules will be missing as a technical container.
Transfering the idea of angular components to business components, I would see a business component as a sub tree in the applicatoin's dependency graph.
