NHF – new heroes for Heroes V 3.1.

It's not critical to fix temp_name right now. It can be fixed later. Also, the city coordinates need to be changed to the gate coordinates. Besides, I forgot to update the special ability description :)
And the Nergal city - Shaman - that's cool!)
I'll have to give the Dark race a name - they definitely need one.)
The color of Hafad's plague should be a cold effect: blue, purple, cyan, gray... Purple-indigo would probably look good.
By the way, it would be useful to change the informative message to the creature's name + the number of creatures killed. There is an array for storing the names of all creatures in the scripts.
