Subject: [PATCH] Applied Dan Miller's fix to use new Robtex API
 (http://seclists.org/nmap-dev/2013/q2/1).  I had to modify it slightly to
 allow [a-z]+.robtex.com in the pattern rather than just dns.robtex.com
 because many entries used host.robtex.com, top.robtex.com, etc.  More
 improvements to follow.

Originally committed by fyodor but recommitted by david after recovery
from backup.
