Added "export-map <filename>" console command to the region server that will export a jpg image of the world map covering a 20 X 20 regions area centred on the current active region (ie the one set with change-region). While this should work in grid mode (if using the grid asset server and if my last commit did fix the world map), you might need to call the "export-map" command then wait a little while (60 seconds?) and then call it again so that you make sure the region has got all the texture assets from the asset server.
