NHF – new heroes for Heroes V 3.1.

Unfortunately, I don't know how to add new characters to the list of heroes available for selection in the editor.

All objects in the editor are stored in the index.bin file. This is the only file in the game that, when inside the map archive, merges with the original file instead of replacing it. If you put the original file into the map, it will be modified when new objects are created. This is how I added the city and buildings of the Dark Elves to the editor panel.
