feat(fls): import switch, wireless, routes, RIP and firewall settings

importProject carries the system software settings into the model the
core runs: switch SSID and learning time (an SSID Java would roll comes
from the node id, as in Swift), a host's wireless network, manual routes,
RIP and the firewall of every router and home router. The Swift oracle
writes these settings too; they match on the 13 files Swift reads
completely.

A router's default gateway — its first interface's, which Java routes to
(Weiterleitungstabelle.holeTabelle) — is imported into the router's
device configuration. Swift's model drops it; in internetwork_komplett
the way back from 141.99.5.10 depends on it. A test pings across three
routers in the core, with and without it.
