feat: F4.6g3 a computer's firewall window, measured against Java's with traffic from two networks

Browse Source 
The firewall-pc scenario and FirewallWindowRun use Java's window as a person
does and send a ping, a TCP connection and a DNS question from the server's
network and from behind the router after each step. The core adds and
removes port rules (personalFirewall.ts) and writes both into the firewall's
log, which now carries each line's time; the room takes the window's
actions and sends its view and the log as lines; the editor shows Java's
window with its two tabs. Not adopted from Java: any integer as a port,
a port after a space refused without a word, a log one can type into.
