feat(sim): F4.6f1 what a run leaves goes back into the document

Browse Source 
The oracle SaveAfterRunRun saves Java's project after a run. The room writes
what a run leaves that Java keeps - files, running servers, virtual hosts,
mail servers' domains and accounts, mail programs' accounts and folders,
firewalls, DHCP clients' addresses - into the document as origin 'sim', at
most once a second, after each action and at the stop; writeRunState writes
only what differs. The command line now goes on in a folder made before a
restart, as Java's does.
