Modified _split_url_string to handle multiple instances of the same parameter. This is useful for APIs such as the LinkedIn search API using multiple instances of the "facet" parameter. Also updated get_normalized_parameters to handle the new datatype returned by _split_url_string (list of tuples instead of dict). It doesn't break from_request but it doesn't make it possible to use multiple instance of the sameparameters in from_request. (as they are stored in a dict in that function)
