Heroes 3 all official campaigns mod

These are all the official campaigns released by 3DO, which include Restoration of Erathia, Armageddon's Blade, Shadow of Death and Heroes Chronicles.

It's compatible with most likely any version of Heroes of Might and Magic III Complete.
Not compatible with Heroes of Might and Magic III HD Edition, unless the company adds all the features and content from the Complete edition to it.

Included features:
* They are compatible with the Horn of the Abyss mod, the HD+ mod and perhaps other mods.
* They are custom campaigns so you don't have to complete previous campaigns to unlock them.
* I have sorted them inin chronological order, so you can better follow the plots.
* I made it so that you can choose your desired difficulty for campaigns that originally had difficulty locked.
* I've fixed the campaign start music to properly play the Neutral or Evil theme for Neutral or, respectively, Evil towns, instead of the Good theme.

The maps themselves are unaltered from vanilla and I've done some testing. Haven't encountered any gamebreaking bugs, but please report them if you do and I'll do my best to fix them.

If you disagree with any changes I made, you can make your own version with relative ease by following the instructions here.
