Network upgrade and new reconnection mode:
* users can disconnect or close app without game progress loose now;
* disconnect dialog will show active tables stats and additional options;
* all active tables will be restored on reconnect (tables, tourneys, games, drafts, sideboarding, constructing);
* user must use same server and username on next connection;
* there are few minutes for reconnect until server kick off a disconnected player from all player's tables (concede/loose);
* now you can safety reconnect after IP change (after proxy/vpn/wifi/router restart);
