Removed the call to convert to html - this is handled by the new news.tcl script. news.adp was previously shared by all the "display news" pages, so I decided to have the conversion to html done in the shared include script, too.
Changed to use richtext and a bit of other clean-up. Tested news item create, edit, upload from file, notifications, rss, view, admin view, etc for PG. Testing for Oracle is next and if bugs are found, there will be a commit soon.
