GetUserFriends throw casting error

In trying to retrieve my friend-list, I'm getting the Exception below. I tested several other methods successfully, so I know auth isn't an issue here.

'foursquare.GetUserFriends("334497")' threw an exception of type 'Newtonsoft.Json.JsonSerializationException'
base: {"Error converting value "21ac47b2cca3eba81920042c710541a5058336f8" to type 'FourSquare.SharpSquare.Entities.FourSquareEntityItems`1[FourSquare.SharpSquare.Entities.User]'. Path 'response.checksum', line 1, position 25143."}

I found the cause... the issue is on line 119 of SharpSquare.cs, when JsonConvert tries to deserialize the JSON it just received from the server, it throws the error below:

Error converting value "21ac47b2cca3eba81920042c710541a5058336f8" to type 
'FourSquare.SharpSquare.Entities.FourSquareEntityItems`1[FourSquare.SharpSquare.Entities.User]'. 
Path 'response.checksum', line 1, position 25143.

This is happening because Foursquare is returning a "checksum" element which is not expected in the deserialization. When removed the checksum element from the JSON, the error above goes away. It's possible that this is a newly introduced item to the Foursquare API.
