Subject: 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.
