ping multiple Ips with python

[darrell]

Didn't mess with the checksum since it works and it's fast enough.
The pyrex code was cool to look at.

Added the following and a thread to improve responsiveness.
Using ipRange(), you can map your network.
Someone could find some traceroute code and find rounters.

I don't need this for hacking. It will help some of my customers.
