Restructure the Routing

[KevinStarWars]

The routing of the template does not follow the best practices. It is chaotic and does not have a clear structure. Additionally it does not use Lazy Loading, which it should as a template for enterprise software.
These tasks derive from the chaotic routing:

• Structure the routing by feature areas
• Use Lazy Loading in order to load feature areas and their features lazy
• Use the RouterModule’s full capabilities and use canActivateChild in order to guard
• Remove routes, which are configured multiple times
