Changing docblock indentation rule.

Doc block indentation must match the surrounding block. Doc blocks for class method definitions must therefore be indented once to match the method itself, like so:

```php
<?php
/**
 * This is a controller. It does stuff.
 */
class Controller {
	/**
	 * Very fancy class method.
	 *
	 * @throws NotFoundException
	 * @param string $id
	 * @return void
	 */
	public function admin_edit($id = null) {
		// ...
	}
}
```
