Mark visited panorama hotspots

For VR Tourviewer 1.0.220 and later

A check mark can be shown on hotspots that link to panoramas that have already been visited.

You can set this globally in the VR Tourviewer Settings menu, with 'use 3D arrow hotspots', or you can override the global setting by adding one of the following User Data Tags in the first panorama of the Pano2VR Tour Browser. Note: the first panorama of the Tour Browser doesn't have to be the start panorama.
