AF83::Decorator::Link: Change #class? to #default_class

Instead of checking for an existing class and then setting the class,
provide a method to set a default class when one hasn't been defined.

This does effectively the same thing but moves the condition inside the
method.

Thanks Johan for the suggestion!
