Controller call model method find_by_director.

Now the controller passes the first example of its spec.
That means that it calls the model method to find similar movies.

A link to this functionality was also created at the movies details page.

An empty view was created for the controller action find_similar.

The spec for the movies_controller was also created with 3 examples,
    only one is implemented so far.

A route to find_similar action was also added to the routes.rb.
Implemented the tests for the other 2 exemples.

Also changed a controllers instace variable name.
