As mentioned, I found the recent_list.wml code incomprehensible. So
I decided to refactor it completely. The result of this refactoring are
the attached files recent_list_security.wml and recent_list_common.wml.
As the filenames indicate, this is not a complete replacement, yet. So
far this only covers security, not News or events. But I think it already
demonstrates the value of the excercise.
