Open alpha testing of the 5.0 HD mod (online lobby).

Excellent work. Thank you, Baratortch! For those who have internet connection issues (like me), this online lobby is simply amazing. Connecting directly in the game with automatic reconnection without Hamachi or TeamViewer is brilliant! And everything works perfectly; if there are any bugs, they are very minor and insignificant, and we will identify them later. I believe this version should become the default one. This is a huge step forward for Heroes 3.
