Allow multiple attachments in discussion posts. Different edited versions can include different (or the same) attachments.
Work still required: clean-up interface, change storage of versioned attachmenturl, message and subject in .db file to XML, add interface for course coordinators (i.e., for lonnet::allowed('rin',$crs)) to display old versions of posts.
Known issues: Edits are not currently stored for bulletin board posts.
