NHF – new heroes for Heroes V 3.1.

We haven't reached cities yet, but I would like all this to be included in another mod, even new buildings.
Regarding the ".exe" file – it’s a real pain.

Based on what was said, an idea arose:
If the opponent has developed the same school (or the opposite one, for magic, for example), then apply a bonus or debuff to the enemy. Although, I don't know; it seems somewhat strange.
