Bug and Fix in isp.py in BT4

While trying to learn more about BT and it's many tools, I discoverd a small bug in one of them
This lead to trying to find a fix for it. I suppose that I was successful.

The tool in question is isp.py locate in ~./pentest/misc/
Upon trying to run the default command one will get the following
------------------code------------------------------
root@bt:/pentest/misc/isp# python isp.py
Traceback (most recent call last):
File "isp.py", line 10, in
conf.verb = 0
NameError: name 'conf' is not defined
root@bt:/pentest/misc/isp
------------------code------------------------------

So to fix open up the isp.py in a text editor and locate the following line near the top from scapy import * and change it to from scapy.all import* and exit.

Now try running again.

------------------code------------------------------
root@bt:/pentest/misc/isp# python isp.py

Usage: isp.py [alternate DNS server on the Internet]

WARNING: this gives false-positives when run behind some NAT
routers! If anybody has an idea of how to prevent that, please
leave a comment under the blog post explaing how this tool works:
