Title: Add help option to form fields

Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes

It adds a help option to form field types as basic described here

http://symfony.com/doc/2.0/cookbook/form/form_customization.html#adding-help-messages

Now you can pass the help option in the form type
```
$builder->add('message', 'textarea', array('help' => 'Enter your bug describtion here'));
```
