Lobby.js update

This update fixes sorting issues, no duplicates, no flashing on update. I tested with every table option and it didnt see any issues. 

I'm using 
vm.games.removeAll(); 
to clear games list instead of 
$('#pokerFilterTables .table').find('tbody').empty();
after clearing games I use ko.applyBindings(vm, $("#pokerLobby")[0]); to rebind table. This method prevents the flashing. 

Please let me know if you see any problems.
