Doing mapping with an external editor

1. Copy the map file to your workstation.
2. Load the map with the editor.
3. Copy your changed  map onto the server with a temporary name.
4. Warp to the temporary map name. Because there is no instance with that name yet, the server will create one based on the file.
5. Test the map.
6. When there are errors, go back to your map editor, replace the temporary map file and use the reset_instance command to reload the map instance.
7. When the map is OK, replace the original file and delete the temporary one.
8. Use reset_instance on the original map to activate the changes. Alternatively, restart the server.

An external version control system like git is needed to care about revisioning on the server.
