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.
