NHF – new heroes for Heroes V 3.1.

In H5_Game_NHF, the executable has been patched for "flyby, combat, and town scripts," "max artifacts count," and "new creatures framework," at least according to what the deflector claims. There might be other patches as well. I think that if this is the complete list of changes to the executable, then nothing prevents us (except for free time) from patching the executable with Mr. Q's AI in the same way.
