add search as a separate component.

- the local test fails, if the model is missing. I should have been generated, but I didn't figure out why not (Rails::Generators.invoke('cms:scaffold', [class_name, '--title=Page: Search', '--attributes=show_in_navigation']))

- the profile page is adapted to work without the search page link (gsub-thing)

- the integration test is still not working for me, I always get these ruby errors. so that is pretty much theory.

- the search box has been added in the right column instead of in the top menu. without additional css, it didn't look good at all on the top menu. We should either use the right column box OR add a bit of css to make it look alright in the top. I think the right column works better regarding the no-css-policy.
