this should fix any of the crashes w00t outlined where User::MyClass == NULL.
The simplest fix seems to be that if the user has no class, skip all the code that uses the class values.
This makes sense because the only situation where User::MyClass == NULL is when they arent authorised to connect and are being quit so checking flood levels and max sendq etc are irrelevent.
