if no internet cnx when go online
if this case, we have a window for each active account which says "couldn't connect to server_jabber_name". i suggest don't show this windows but put it in log, and continue to try to connect.
for example : i start my computer, gajim is launched before my cnx and i always have this windows. i have to close them and go online. more pleasant if gajim wait and go online within my intervention.
