feat(core): FILIUS' web server and web browser after Java, measured against Java

The servers share ServerAnwendung's frame (server.ts); the web server serves
/webserver with virtual hosts, the browser loads a page and its images over
one connection to port 80 (web.ts); HTTP in Java's text form (http.ts).
WebRun records eleven stories on the new web-lan network, with the server's
files; webJava.test.ts plays them card by card. A program's close is a
request, as Java's schliessen. Not taken from Java: /../ serving any file of
the host; an unreadable request closing the connection without a word.
