The post/pre test version of scorm.com's golf course crashed the RTE. I
tested on MGH's Ilias install and it crashed it as well, so it's not something
we've introduced in our porting effort. I've fixed it, it involved improper
handling of the children of invisible nodes in the activity tree. I've also
made it possible to put all script file references in the document's HEAD
section. The initial call to scorm_init is still in the body and should
probably be moved to a function and called by an onload() event.
