feat(fls): write the installed applications of a .fls, loaded by Java as the original

Browse Source 
topologyWriter.ts puts each installed application of a PC or notebook under
its key and gives it the system software, as installApp does, with its
settings: a server's switch and port, a client's target, DNS recursion,
virtual hosts, the peer count, the personal firewall. The applications
follow the files, as in Java's own files: the web server, the peer-to-peer
application and the e-mail server make their directories only where the
files lack them, and the DNS server reads /dns/hosts when it is installed.
E-mail accounts, messages and address books are the next step.

The Java oracle now reports a personal firewall's rules in full, not their
number (the corpus has none; its result is byte-equal).

Checked by Java against Java: every corpus file, read and written again,
loads with the same applications as the original. The synthetic topology
adds every FILIUS application with settings away from its defaults, a
personal firewall with a rule, an own index.html (Java makes no second) and
a missing /peer2peer directory, which Java makes at the end. 12 mutation
probes, among them files and applications in reverse order, each loaded by
Java, were all caught.
