Settings callback for foo filter.

Make use of $format to have different replacements for every input format. Since we allow the administrator to define the string that gets substituted when "foo" is encountered, we need to provide an interface for this kind of customization. The object format is also an argument of the callback.

The settings defined in this form are stored in database by the filter module, and they will be available in the $filter argument.
