sr=rpotts. cookie/wallet r=morse, xmlTerm r=saravn@mozdev.org, mailnews r=mscott, activeX r=adamlock, everything else covered by the sr from rpotts. 15345. These changes remove nsIDocumentLoaderObserver.idl from the build, and all of it's implementations and registrations have been moved over to nsIWebProgressListener.idl and nsIWebProgress.idl respectively. there are two (78762, 78760) mailnews printing bugs that I overturned *before* landing this. I've run this code through the mail-news and browser smoketests among other tests outlined in the patch description attatched to the bug.
