[SqNOS] Screnshot: SqueakNOS showing received packets

[Gerardo Richarte]

I just added a new Screenshot of SqueakNOS receiving packets using IRC,
and showing them in the Transcript.
For this we're using NetSqueak (http://www.squeaksource.com/Net.html)

https://sourceforge.net/project/screenshots.php?group_id=3891&ssid=37701

You can see the first packets are ARP requests, then and ICMP
EchoRequest (ping) and then an incoming TCP SYN request to port 23.
Packet sending is not implemented yet, so I had to manually set the mac
address using 'arp -s' on the source box.

The screenshots are shrinked for some reason, but if you take a close
look, you can see #handleIRQOn: and the Transcript nicely showing the
Packets with a very nice print string.

>From now on you will need to grab NetSqueak from Monticello too in order
to properly build SqueakNOS. It's not really necessary yet, but if you
want to "Computer current defaultNetworkInterface enableInterrupts", you
will either have to modify LanceNICDevice>>handleIRQOn: or bring
NetSqueak in.

    as usual, enjoy as much as you can! :-)
