Title: Added "helper" functionality

This PR enables us to do

````
$this->helper('DependencyInjection')
````

to retrieve special helper classes. It is inspired by the IcBaseTestBundle.

Helper classes can implements `ContainerAwareInterface` to have access
to the container.

Have included a helper for DependecyInjection to help with schema validation.
