Subject: Show map tile for hyperlinks. Perform Check4096 before adding a
 hyperlink.

Configuration option AssetService in section [GridService] must be set to enable this functionality.

Map tiles do currently not show for hyperlinks set in simulators that are connected to grids, see Mantis #5270.
