/*
	Filter all fields and all rows in a recordset and returns the 
	processed recordset. We scroll to the beginning of the new recordset
	after processing.
	
	We pass a recordset and function name to RSFilter($rs,'rowfunc');
	and the function will be called multiple times, once
	for each row in the recordset. The function will be passed
	an array containing one row repeatedly.
	
	Example: 
 	
	// ucwords() every element in the recordset
	function do_ucwords(&$arr,$rs)
	{
		foreach($arr as $k => $v) {
			$arr[$k] = ucwords($v);
		}
	}
	$rs = RSFilter($rs,'do_ucwords');
