feat(editor): F4.6d the web browser and web server on a computer's desktop

The oracle BrowserWindowRun uses Java's browser and web server windows as a
person does; the room keeps a browser window per computer and sends a
program window's view, the start names the person's language. The editor
shows the page in a sandboxed frame, links and forms go to the room, the web
server has its button, virtual hosts and lines. Better than Java: relative
images and links count from the page's folder, a mark stays in the page, the
error page from Java's template, the virtual hosts' file with complete rows.
