Significant refactor. Moved the tcl code out of the .adp file and added dynamic expand collapse if the browser supports javascript. Works on non-js browsers too. The tree building still isn't as clean as I'd like, this probably requires a recursive function to do cleanly, but it works and is IMHO a vast improvement over the previous version.
Retrieve and include header stuff from global variable dotlrn_master__header_stuff. This is helpful for portlets that use javascript, e.g. dotlrn-main-portlet, and gives us a way to do it without having to ship the javascript on every page.
Fix: Import QTI text following the texttype attribute.If texttype is text/plain we convert to HTML and if texttype is text/htmlwe get it raw.This way all the text fields in the database are always HTML
