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.

// Uses FILIUS' own web browser and web server windows
|

// (GUIApplicationWebBrowserWindow, GUIApplicationWebServerWindow on their
|
||||
// GUIDesktopPanels) on web-lan's network as a person does: an address typed
|
||||
// into the browser's address line and Enter pressed, a link clicked (the
|
||||
// event Swing's HTMLEditorKit makes of it: the href against the document's
|
||||
// base), a form's button pressed (the real button Swing draws for it), and
|
||||
// on the server's window the start button, the virtual hosts' check box and
|
||||
// table. After each step it writes what the windows show: the browser's
|
||||
// address line and title, the page its program handed the window; the
|
||||
// server's button, check box, table and log, and the requests it got. The
|
||||
// reference for the editor's browser and web server windows
|
||||
// (packages/sim/test/browserWindow.test.ts).
