Created downOrNot.cgi - cgi-ified version of Python guts checked in earlier

Additional removal of extraneous comments, error handling, CGI HTML prints moved to the bottom of the file, other cosmetic improvements.

To do:
1)Differentiate between down, unregistered, and invalid domains. (Implemented in DFJM)
2)Attempt ICMP traffic as well as other checks to differentiate between downed webservers and completely unresponsive/unreachable addresses. (Not implemented in DFJM)
3)Utilize logic coded in domainRetrieveFromURL() and domainRetrieveFromFQDN() to check "super domains" of domain requested.
4)Make functions listed in 3 recursive.
5)Make hysterically ugly webpage prettier.
