crashes. This should fix several of the mailnews bugs. It's hard to say exactly which of them will be fixed by this, since some of them are caused by memory whackage and others are real bugs in the widget itself. Also adding in support for Troy's primary frame hashtable, thus ensuring that when the tree widget dynamically deletes frames that the mappings in the hashtable are removed (so that deleted frames won't accidentally be retrieved).
