Title: Update validation.php

Old explanation was not true at all, not even close, after saying to use attribute_rule was changed to use attribute.rule but actually it's:

```php
'custom' => array(
'attribute' => array(
'required' => 'message',
'alpha' => 'message2'
)
)
```

I had to check on Validation class to figure it out
