changed internal port from string

Isn't it silly to store port as string? I think so...

added ability to resend packets that were not acked

I added ability to resend packets in a message that was not acked by a peer.
packets are resent after 5 seconds automatically. Unfortunately the order of messages
is not gaurenteed yet for UDP connections..

removed disconnect message from session

The UI now does not announce when a user disconnects in a session tab. Because we now
have auto reconnect, you can leave a session tab open for days and still successfully reconnect
to a peer and have the session applications communication restored. Since the user
turns red when they disconnect and since it is already announced in the alert tab, I
thought this message was silly.

The message when a user explicitly quits a session is still there.
