nsPresShell now listens to changes in the domselection. (also modified nsIEnumerator to use NS_IMETHOD instead of virtual nsresult). Added batching for selection changes. you can move the selection, do things then turn off batching for an update if necessary. also prevented circular referencing by adding listener removal to PresShell::endDocumentListening(sp)
