Refactor "Authentication" class with four main methods:

Browse source 
- withSession() - for auto authentication with Session/Cookie variables
- withOpenId() - for authentication with an OpenID account
- withPassword() - for authentication with Password
- setForUser() - for setting the user auth context of the current session

Refactor "Session" class - contains now "native" Session Management methods
