dmiller 31bc2847bd Normalize script author fields 
Clean up some typos and differences. Most have been normalized to
whatever form of the name occurred in the largest number of scripts.
Paulino was contacted directly and requested his email be added to all
of his credits.

Performs a domain lookup using the edns-client-subnet option which
allows clients to specify the subnet that queries supposedly originate
from. The script uses this option to supply a number of
geographically distributed locations in an attempt to enumerate as
many different address records as possible. The script also supports
requests using a given subnet.
