Groupie

Hey Everyone,

Groupie is switching to a new "Charm Validation" technique and getting rid of the ugly hashes -- like "[#Ag4f]" at the end of messages.

Instead we're using 3 target markers. The idea came from @haste.

You may see some "Fake News" responses from people who haven't updated yet. Hopefully it won't take too long to get everyone updated.

Cheers!
