feat(editor): F4.6c the software installation on a computer's desktop

A new oracle, InstallRun, installs each of Java's programs on new
computers, all of them on one, each installed and removed again, and a
DNS and an e-mail server installed again after their removal; Java saves
the result as a project. A new program is switched off (a computer's
firewall is on), makes the folders and files it lacks (the web server's
start page in FILIUS' language and its picture, /peer2peer,
/mailserver/konten.txt, /dns/hosts), and removing it takes its settings
and leaves its files; a server installed again reads its records or
accounts from them. Java installs in the order of its list and starts
the program at once.

The document's setSoftware does the same, checked against Java's saved
installation. The core knows what a program makes in the files and
installs or removes a program while the simulation runs; the room
watches the document's programs and hands changes to the engine, so a
new command line works at once. The desktop offers Java's dialog with
two lists, arrows, double click and apply changes.

Also: Java's file may name a number it rolled by the result of any
getter (an idref, here a thread's priority); GetterDefaults now
measures the priority of the saved thread classes, which the import
read as 0 before.
