feat(fls): system software settings as Java loads them

readSystemSoftware adds to each node what the topology needs from its
system software: a switch's SSID and learning time, a host's wireless
SSID, a router's RIP switch, the manual routes and the firewall of a
router or home router. All 23 corpus files match Java.

- A router's firewall is one object its constructor hangs in two places;
  the corpus writes it under the web server's "konfig" plug-in. The
  places are merged.
- The decoder keeps entries a constructor made in a map, reached by
  get(key) (installed applications), like the elements of a list.
- The Java oracle loads every file twice and writes values that differ
  as null: what FILIUS rolls (MACs, a switch's SSID) without text search.
