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

the offline update to alpha 53 is available at the same link

+ The timer now pauses during reconnection.
+ In-game chat now becomes private for two-player games.
+ You can now view a player's rating by right-clicking on their name in the player list.
+ The 6LM-8MM mix template has been added to the RMG template list.
- The restriction on using the lobby for foreign players has been removed, meaning you can now enter the lobby with an English HoMM3 version on a non-Russian Windows.
+ Optimizations and bug fixes on the server and client.

! For SoD, the debugging functionality that accidentally made it into the alpha release, which automatically filled in the opponent's password, has been removed.
New password-protected saves are not compatible with previous (compromised) versions of HoMM3 HD, and vice versa.
Save encryption has been changed.

This alpha version is now as close as possible to a beta version in terms of implemented functionality (and in terms of stability, it's close to the final release). Either the next version or the one after that will be released publicly with an over-the-air update.
