feat(fls): installed applications as Java loads them

readSystemSoftware lists a PC's or notebook's installed applications with
the settings the model needs: server applications switched on and their
port, the generic client's target, DNS recursion, web server virtual
hosts, Gnutella's peer limit and the personal firewall (on by default,
unlike a router's). Defaults the file leaves out are measured in Java.
All 23 corpus files match Java.

Two examples install an application of their own (Accumulator,
Broadcast), compiled into projekt/anwendungen; it is left out with a
warning, as this reader cannot run Java classes. It must survive a save.
