HoMM IV Reference Guide.

I didn't plan to do it, but then an idea came to mind (regarding the speed of completing the game), and I also gathered more information. I mainly added to the first part; many sections were affected, and I even had to divide the last section into two. I also added a section with artwork from the upcoming expansion at the very end. And in the sections about the factions, I highlighted sections called "Opponents" for each faction. I didn't have to fix any errors; it was mostly about clarifying and refining things. And then I tidied everything up (edited it), trying to remove all duplicates and sort out the confusing wording. Overall, I reworked it significantly (apparently, I was inspired), and there are many useful differences from the previous version, so I even deleted the previous version and kept this one as the final version.
