A virtual aid (AIS message 21's VirtualAtoN flag) is a mark broadcast where nothing physical stands, so drawing it as a buoy showed a mark that is not there. The vessel source record now carries `virtual` (false unless a source says true; any source may set it), AISStream sets it from VirtualAtoN, and the vessel layer keeps such an aid's disc: vesselModelSpec returns null for it and the layer gathers no model item for it. Its card, selected card and readout add VIRTUAL after its kind.

- Draw aids to navigation as buoys instead of ships: a buoy, beacon, RACON,
light or mark from the vessel feed (or any AIS station numbered 99MIDxxxx)
is now the fleet set's buoy of its IALA mark (cardinal, port or starboard
hand, safe water, isolated danger or special mark), standing still with no
heading, and its icon is a disc rather than a chevron. Its card and readout
show its kind of mark with no speed or heading. AISStream now subscribes to
aid-to-navigation reports and names each by its kind of mark and its full
name; the feed lists every ship ahead of any aid, and
vessels_in_areacounts ships only. A virtual aid (a mark broadcast where nothing physical stands) keeps its disc, is never drawn as a buoy, and its card says it is virtual; vessel sources may mark any recordvirtual(samehkhamis, #1733).
