Heh, well I didn't thing it was a terrible idea :).  Sometimes you
want to be stealthy and blend into the crowd.  But at other times
there is value in being above-board and stating that we're Nmap NSE
and damn proud of it!  Right now I think the our http library user
agent is just "Nmap NSE".  I think we should at least use a more
standard format.  Here is what Yahoo uses:

Mozilla/5.0 (compatible; Yahoo! Slurp/3.0; http://help.yahoo.com/help/us/ysearch/slurp)

We could use something similar:

Mozilla/5.0 (compatible; Nmap Scripting Engine; http://nmap.org/book/nse.html)

Unless someone has a better idea, I'll change it to this for now.  If
a bunch of idiots start misunderstanding and thinking it is me trying
to hack their server just because I host the NSE documentation page,
the URL is going away.  Or maybe I'll just change it to sco.com or
microsoft.com :).

I agree that it would be nice to have an NSE option argument to set
your own user agent.

Cheers,
-F
