for teh moduleManager

- The authentication controller now uses the Authentication/Manager class,
also there were some issues in the Session creation, this has been removed
from the Bootstrap now, as the Controller must decide how to open a session
(read-only or read/write).
- The tests reflect a few chagnes, as the move from the CSRF token generation
to the Formbuilder.
- Notificaiton now doesn't use Zend Session
