not always: after logging in normally, switch goes off and:
09-21 01:34:17.280 19704-19742/de.adornis.Notifier E/ADORNIS﹕ SmackException while connecting in Listener null
09-21 01:34:17.280 19704-19742/de.adornis.Notifier E/ADORNIS﹕ << disconnecting
some other random cases :D
bad? normal? no other options?
display connection timeout when connecting, from main screen and from settings.
distinguish server down or user side failure?
fix with connecting multiple times?
