"www" removed from hostnames

We have removed “www.” from all hostnames on Moodgeist. It saves four bytes/characters of typing and just looks nicer this also affects the ping API. If you had a Pinger client running, update it to ping against the new endpoint without “www.” in it. (UPDATE: actually the old URL-s still remain working for now… but you may want to update anyway, as the ones without “www” are just nicer.)
