feat(editor): F4.6a simulation mode and a computer's desktop

Java's mode buttons start and stop the room, now in a worker of the
editor's page (LocalSimHost), with Java's speed slider. While the
simulation runs the design is locked as in Java: no palette, no sheet,
nothing moves, no undo. Cables that carry a frame light up in Java's
green, and a tap on a computer opens its desktop: Java's title, the
software installation first, then the installed programs in the order
of Java's list for the language, a taskbar with the network icon and
the network as the simulation runs it. The room sends that over a new
topic, node:<id>. Desktops stay over a return to the design and show
again at the next start. The programs' windows follow from F4.6b.

/* A computer's desktop after Java's GUIDesktopPanel: 640 × 460 pixels below

* for a finger, Java's has 30), icons of 120 × 96 with white names on Java's
* background. On a phone it fills the surface. Java's colours stay in both
* themes: the screen is the simulated computer's, not the editor's. */
