Add jdf mail lists into search.jboss.org

After http://www.jboss.org/jdf/ has been released we can bring the two following mail lists into the search.jboss.org:

jdf-dev: https://lists.jboss.org/mailman/listinfo/jdf-dev
jdf-users: https://lists.jboss.org/mailman/listinfo/jdf-users

We need to think where these two mail lists fit in terms of filtering/search criterions.
