New utility functions for working with the internal rule format.

2000-02-22  NotZed  <NotZed@HelixCode.com>

        * filter-xml.c (filter_clone_optionrule):
        (filter_clone_optionrule_free):
        (filter_optionrule_new_from_rule): New utility functions for
        working with the internal rule format.

        * filter-arg.[ch]: Added new callbacks for editing a single value,
        and a new editor which shows all items in a list, and allows you
        to edit them via the single-edit method.  This needs some cleanup
        for some unused/unusable virtual methods (edit_values,
        write_html?).

        * Makefile: Add the druid for build.

        * filter-druid.c: A 'druid' widget for editing a single filter
        rule.
