Server optimization

In connection with the Mind Sports Olympiad, I decided to optimize the game server and removed the move information from the game side: each move was about 100 bytes, so when you enter the Mind Sports Olympiad tournament room (or refresh) in the middle of the game, you were sent about 300kB of data (100 bytes X 100 ongoing games X 30 moves for each game). The result is that there is no move window anymore when looking at the game. I guess no one misses that. In connection with this, quite a lot of code had to be refactored on the server side and errors may have occurred in the following games: 1) Chess 2) Gomoku (with color change) 3) Renju ( Taraguchi) 4) Podkidnoi 5) 4-person perekidnoi 6) Sudoku (duels) 7) Crosswords (Duels) 8) Duubelda. Please let us know immediately if you encounter any problems with these games! Thank you in advance for your understanding!
