feat(core): the pages of routers and home routers after Java, measured against Java

Browse Source 
Routers and home routers start a web server on port 80 with Java's index,
log and routes pages in the project's language (routerPages.ts); the
firewall keeps a log per node that outlives a new start; RIP routes carry
the telling router's public address. TCP counts sequence numbers and
segments in Java's characters, not bytes. RouterWebRun records six stories,
with firewalls now built by ScenarioNetwork. Not taken from Java: its router
server sometimes never listening (a race in setAktiv), and </titel>.

// Runs a story with the web pages of FILIUS' routers and home routers: each
// starts a web server on port 80 with its own index page and the plug-ins
// log (the firewall's log), konfig (the firewall's settings) and, on a
// router, routes (VermittlungWeb: forwarding or RIP table). A host's web
// browser asks for them; recorded are every frame each card saw, the
// router's web server's window lines and everything the browser told its
// window.
//
// RouterWebRun <scenario.json> <story> <milliseconds> <out.json>
//
// router-web (router 10.0.0.1/20.0.0.1 with a firewall: drops ICMP,
// accepts TCP to port 80 from 10.0.0.0/24; browser on 10.0.0.2):
// routerIndex 10.0.0.1
// routerRoutes 10.0.0.1/routes (the forwarding table)
// routerLog a ping to 20.0.0.2 (dropped), the index, then
// 10.0.0.1/log
// routerKonfig 10.0.0.1/konfig
// nat-home (home router 42.0.0.10/192.168.0.1):
// gatewayIndex from the LAN PC 192.168.0.10: 192.168.0.1, then
// 192.168.0.1/routes (no such page on a home router)
// gatewayFromWan from the WAN host 42.0.0.20: 42.0.0.10
// rip-chain (three RIP routers, each seeded as RipRun seeds it):
// ripRoutes from 10.0.1.2, after 40 s: 10.0.1.1/routes
