Sass joke cmd upgrade

[ghost]

!sass @user

Ideas include tagging the user in a sassy message, sassing the user and then muting them for 10 seconds, or random variants of a sass message. This would ideally be a decent gag and not an admin command, probably in the chatter.js file in discordlib (or whichever novelty code file replaces it someday)
