Fixed setting of families in Configurator
Renderer no longer triggers directly on setup finish.

- Since the Routes all end up triggering Renderer:render anyway,
  it's not helpful that the Renderer renders on setup completion by itself anymore.
  Instead this led to the Renderer rendering the page twice right after setup.
Removed LinkInterceptor

- The LinkInterceptor was outdated, and therefore removed.
Fixed de-/selecting languages by using the checkbox for a whole family.
Added more routes.

- This adds more flexibility to the route layout and reduces errors with displaying content.
- Relevant for #25
- I still have to fix the initial loading of the study requested in the route,
  for cases where it's not in localStorage.
