Implemented by

 This interface is used to display a confirmatino dialog before
 launching a "helper app" to handle content not handled by
 Mozilla.

 Usage:  Clients (of which there is one: the nsIExternalHelperAppService
 implementation in mozilla/uriloader/exthandler) create an instance of
 this interface (using the contract ID) and then call the show() method.

 The dialog is shown non-modally.  The implementation of the dialog
 will access methods of the nsIHelperAppLauncher passed in to show()
 in order to cause a "save to disk" or "open using" action.
