Anonymous Voting causes object error

If an anonymous voter tries to vote again or change their vote, it causes an error in the votingapi modules since it passes a value instead of an object, as votingapi_change_vote expects an object, not a value.

Need to change the db_result in or near line 270 to db_fetch_object

--if ($old_vote = db_result(db_query("SELECT vote_id FROM {votingapi_vote} WHERE content_type = 'node' AND content_id = %d AND value_type = '%s' AND tag = 'vote' AND uid = %d AND hostname = '%s' AND timestamp > %d", $nid, $vote->value_type, $uid, $hostname, time() - (60 * 60 * 24)))){ // existing votes from the same IP address within the past day

to

--if ($old_vote = db_fetch_object(db_query("SELECT vote_id FROM {votingapi_vote} WHERE content_type = 'node' AND content_id = %d AND value_type = '%s' AND tag = 'vote' AND uid = %d AND hostname = '%s' AND timestamp > %d", $nid, $vote->value_type, $uid, $hostname, time() - (60 * 60 * 24)))){ // existing votes from the same IP address within the past day
