Duel sets and duel generator.

Small update. Since the game reads this and generates not a map, but dueling heroes, it's best to maintain some order and do things properly. UserMODs/*.zip UserMODs/*.h5u UserCampaigns/*.h5c DuelPresets/*.h5p Maps/*.h5m Therefore, I renamed the generated map and all future ones to dueliki.h5p, and it should be placed not in the Maps folder, but in the DuelPresets folder. If someone is not used to this, they can simply rename it to h5m and place it in Maps as before. I made some minor improvements: for Orcs, not all skills were available; now they all are (Mentorship, Dark Revelation, Distraction, Mana Burst, Fire Protection can now appear randomly; they couldn't before). I fixed a typo that caused Gremlins to appear instead of Obsidian Gargoyles in the same quantity. I removed the combined warcry for Orcs – it's not the most useless spell, but if a hero receives Inspiration in a random distribution, they will be without the Horde Fury due to the small spellbook. I updated the file in the header and removed all the old stuff. (If you need to fight without creatures in NCF, simply set IS_USE_NCF to 0)
