Fix: Custom filter was running through the rows in reverse

* Originally this was done because it makes removing items a little bit
  easier with Array.splice(), however, it doesn't make any sense to go
  through the rows in reverse if there might be an interdependency
  between the rows.
* It has never been documented what order the rows are filtered in, so I
  think this is a safe change to make.
* I've also added the row display index to the parameters passed in
