Title: Horizontal / inline / vertical forms should not be abstract

[Zend_Form array notation](http://framework.zend.com/manual/en/zend.form.advanced.html#zend.form.advanced.arrayNotation) require repeated elements to be subforms. In this use case is required to instantiate form and add it as subform:

```php
$subForm = new Twitter_Bootstrap_Form_Horizontal();
$subForm->setDecorators(array(
'FormElements',
));
$subForm->setIsArray(true);

// ... adding elements to subform

$this->addSubForm($subForm, 'subform_name');
```

Another thing is that it is impossible to create a pure form and configure it using the API.
