NHF – new heroes for Heroes V 3.1.

I was already hoping that some of the new models (or at least just new textures) would be included in this version, but some things are missing. Trollsai, Frida, and others haven't been fixed, and Alaric is completely broken (when he's standing still, everything is fine, but when he runs, he's headless – I didn't have this problem in the previous version), and so on.
