added CancelTimer() method to turn off the timer at a safe time; added NS_GetObjectFramePluginInstance() to access the associated plugin instance with an nsObjectFrame; fixed some attribute accessor bugs, returns an error if an attribute doesn't exist; implemented GetArchive() and GetMayScript(); added GUItoMacEvent().
