Add support for zone transfers and wildcard domains

[invisiblethreat]

I forked this morning to write this, and then discovered that I know a lot less about Go than I hoped. :( https://github.com/invisiblethreat/offensive-security/blob/master/wildcard_domain.py

import uuid
import socket
import sys

prefix = uuid.uuid4()
domain = sys.argv[1]

try:
  result = socket.gethostbyname(str(prefix) + "." + domain)
  print "%s has a wildcard DNS entry" % sys.argv[1]

except:
  print "%s does not have a wildcard DNS entry" % sys.argv[1]

For wildcard entries, detecting them is at least the first step. If a wildcard entry is found I think the sensible thing to do is bail out.

Zone transfers shouldn't be too bad though :)

The wildcard stuff has been done in #10
