Implement a screen showing the results of a game

Currently (with windconditions and reporting) The player just gets a message if he won and in the background eventually the results are transmitted to the metaserver. There is no feedback about this currently.

A fullscreen menu could be implemented to which the player gets when the game is over. There the player can see how the game ended (who won, lost, left the game) and how many points each player got. There should also be information (perhaps on a second tab) about what was reported to the metaserver and what the metaserver did with it (reported, error, no connection)
