change login failed text to include incorrect pw (and timeout?)

[xuiqzy]

in the text that states the connection failed and you should use your jid, include a notice that the pw could be wrong,too: login process failed blub, use your JID AND make sure the password is correct

also show this message when connection failed after entering something in settings and reconnecting afterwards

also include timeout in this mesage or show another message, if connection timed out? would be nice
