[Samba] Lightweight NetBIOS host enumeration in Python

[Matthew Dempsky]

As a quick update, with some off-list help, I've updated the code to
resolve a few interoperability issues that showed up on other networks
and to make some of the error handling more robust.  To anyone who
downloaded version 0.01, I'd appreciate if you gave 0.05 a shot as
well:

Same operation as before: just unzip and run "python nbtls.py".  Test
reports still welcome.

Thanks. :)
