namespaced alias class without ancient autoload..

if you already have a sane autoloader set up for modules, just use this file, call like such:

```php
$purifier = new \HTMLPurifier\Processor();

$html = '<strong>a string<br></strong>'; // (notice the dirty <br> that should be <br />)

echo $purifier->purify($html); // outputs: <strong>a string<br /></strong>

```
