CInlineValidator::clientValidateAttribute($object,$attribute)

Hi.

Propose ti change method to 

```php
public function clientValidateAttribute($object,$attribute)
{
	if($this->clientValidate!==null)
	{
		$method=$this->clientValidate;
		return $object->$method($attribute, $this);
		// or return $object->$method($attribute, $this->params);
	}
}
```

it would help to write more convenient js-validators, using additional parameters, such as $ params ['message']
