Throw a subclass of XmppException when authentication fails because of wrong credentials

At the moment it's only possible to determine cause of authentication failure 
is 
via inspecting exception message. This is a bit inconvenient. Throwing a 
specific 
subclass of XmppException makes more sense.

On these devices authentication often fails beacuse of network failure, timeout 
or 
similar results. Hence it's more (compared to desktop version) important to 
correctly determine failure reason and take proper action. For example warn the 
user his credentials are wrong.
