#2 Add parser for whois.godaddy.com

[Samuel Huckins]

I tried running:

python rwhois.py zenoss.com

And got:

rwhois.py:412: DeprecationWarning: raising a string exception is deprecated
raise 'NoParser for', self.whoisserver
Traceback (most recent call last):
File "rwhois.py", line 933, in <module>
main(sys.argv, sys.stdout, os.environ)
File "rwhois.py", line 922, in main
d.Parse()
File "rwhois.py", line 401, in Parse
self._ParseWhois()
File "rwhois.py", line 412, in _ParseWhois
raise 'NoParser for', self.whoisserver
NoParser for: whois.godaddy.com

GoDaddy is a pretty common registrar these days, would be great if rwhois.py could handle domains they register.
