Title: Validation::add_fields to pass an array containing multiple validation rules at once

This allows us to add multiple rules to a validation object at once with a single array.

Example:

```php
$_validation['login'] = array(
array('username', 'Username', 'required|trim|valid_string[alpha,lowercase,numeric]'),
array('email', 'Email', 'required|trim|valid_email'),
array('password', 'Password', 'required|trim')
);

$val = Validation::forge('login')->add_fields($_validation['login']);
if ($val->run())
{
...
}

```
