When the Body Response in JSON has an error message ({error : "error_message"})

When the Body Response in JSON has an error message ({error : "error_message"}), the resquest method returns nil. Instead of, should return an error message or raise an Exception.

Foursquare documentation states that such messages are sent back with a HTTP status code of 501. The gem currently doesnt check for this status code. That might explain why it doesnt raise an exception. I unpacked the gem and added the following code. Hopefully it should handle this case

add to the function raise_errors

when 501
raise BadRequest, message
