Please no more options to PaginatorHelper methods. If `$tag === false` why couldn't HtmlHelper::tag() just return the contents with no wrapping tag?

```php
$out = $this->Html->tag(false, '<em>stuff</em>');
assert($out === '<em>stuff</em>');
```

Something like this would help reduce some of the duplicate code and make `tag()` less stupid in theory. It may have other adverse effects I can't think of right now though.
