ARCHIVE_CLEANSER: A module that will clean messages before they're

committed to Pipermail.  As this is a standard handler-style module
(i.e. it has a typical process() function), it could be used in a
pipeline to scrub messages headed to the list (i.e. a de-mimer).

Current drawback is that it's fairly hardcoded.  Graft on a U/I
(easier said than done), and it could work.
