Subject: [PATCH] Fix serialization in child classes

Current visibility of properties $email and $charset (private) limits the ability to serialize any inherited class, since __sleep(), when is called in a subclass, cannot access those properties and thus serialization is missing the most important part of class, the email.
Changing $email and $charset to protected addresses this.
