new feature: not trust the server, change: execute turns randomly

[PatrickHechler]

let the server save the entire start world + the random seed. let the server then save all user turns. make turns and entity turns comparable and then sort them before they get randomly ordered and then executed. (sorting before random order needed because it needs to be reproduced after the game end by the users) after the game ended, the server sends the data to all users. (send maybe the data to users when they get defeated)

[PatrickHechler]

save only the start world, the user placer implementation and the worlds random seed give the user placer at game start a sorted list of all users then also the start position can be reproduced #9 (the user placer should then not use random values from other sources then the worlds own random)

[PatrickHechler]

also change the user so that all users are placed when the game starts

• give users before the game starts just an user world (like the current default user placer
• give the user placer the worlds random and all users (sorted) when the game starts
• change the user placer, so that the users get some start entities placed (maybe configurable)
