keyval == keysyms.Tab or keyval == keysyms.ISO_Left_Tab
instead of:
hardware_keycode == 23
so it works under win too.

with high net load 15 secs is not enough. it is important not to give the idea to the user that those contacts that popup in 17 second just signed in cause that is simply not true. So it is better to lose one possible contact logging in the first 30 seconds after we logged in, that to show 3 or 4 contacts just logged in at once

important bug in xmpppy does not allow us to default to tls True. In fact big stanzas result in disconnection. So until it fixed, TLS is *highly* discouraged [maybe we should disable it via GUI] cause I was even able to get disconnection when sending huge text [so not only disco related but allover]
