Remove 'column_class' theme setting.

We used to use individual semantic classes for the types of contents
in each column. In Neue 6.0, we removed this in favor of using a general
`.footer__column` class with two variants ('.-social' and '.-links').

Also removes the "Advanced options" fieldset since it would now be
empty.
