Fix bug #3654. Work on topframe in CSTR with remote. Static /publisher/publisher.html replaced with dynamic lonpubmenu.pm that includes appropriate buttons depending on whether page being displayed in lower frame is a directory listing or a resource. Known issues: modifications required to language files to translate button names (see texthash in lonpubmenu.pm)
