When clicking on a playername in the lobby playerlist, the game where that playername participates or participated should be selected
If the playername is found as an active player, that game must be selected (even if he is present as an offline player or observer somwhere else).
If the playername is not found as an active player but as an observer and an offline player, the game where that player is observing should be selected (so that the user might want to join that game too).
