"HW rulez" mod (add-on) for HoMM3.

With this patch, it is truly more convenient and easier to follow the rules, especially for beginners who might forget which template allows using Dimension Door and which doesn't, which units can be upgraded and which cannot, etc.

For beginners, installing the ND mod and connecting some module is not a simple task. Especially if the guy is a total noob with computers, rather than the game.

But still, it's better than reading the entire list of rules, which makes all desire to play Heroes vanish the first time :D
