Sorting direction as the third argument in onSort

[oskarkrawczyk]

onSort should pass the sorting direction as the third argument.

Original code:

sort: function(index, reverse, pre){
  if (!this.head) return;

  if (!pre){
    this.clearSort();
    this.setSortedState(index, reverse);
    this.setHeadSort(true);
  }

  var parser = this.getParser();
  if (!parser) return;

  var rel;
  if (!Browser.ie){
    rel = this.body.getParent();
    this.body.dispose();
  }

  var data = this.parseData(parser).sort(function(a, b){
    if (a.value === b.value) return 0;
    return a.value > b.value ? 1 : -1;
  });

  if (this.sorted.reverse == (parser == HtmlTable.Parsers['input-checked'])) data.reverse(true);
  this.setRowSort(data, pre);

  if (rel) rel.grab(this.body);
  this.fireEvent('stateChanged');
  return this.fireEvent('sort', [this.body, this.sorted.index]);
}

New:

sort: function(index, reverse, pre){
  if (!this.head) return;

  if (!pre){
    this.clearSort();
    this.setSortedState(index, reverse);
    this.setHeadSort(true);
  }

  var parser = this.getParser();
  if (!parser) return;

  var rel;
  if (!Browser.ie){
    rel = this.body.getParent();
    this.body.dispose();
  }

  var data = this.parseData(parser).sort(function(a, b){
    if (a.value === b.value) return 0;
    return a.value > b.value ? 1 : -1;
  });

  var reversed = this.sorted.reverse == (parser == HtmlTable.Parsers['input-checked']);

  if (reversed) data.reverse(true);
  this.setRowSort(data, pre);

  if (rel) rel.grab(this.body);
  this.fireEvent('stateChanged');

  return this.fireEvent('sort', [this.body, this.sorted.index, reversed]);
}

This change is needed so the correct order can be applied upon reloading.

I see there are 43 open pull requests, so I'm not going to bother with queuing yet another one... Unless you like the change and will apply it straight away, then I'll create a pull request :-)
