command has the bot perform an anonymous action in a given channel, and
the 'say' command allows other people to speak through the bot. Since
this can be fairly well abused, you might want to set
supybot.plugins.Anonymous.requireCapability so only users with that
capability can use this plugin. For extra security, you can require that
the user be *in* the channel they are trying to address anonymously with
supybot.plugins.Anonymous.requirePresenceInChannel, or you can require
that the user be registered by setting
supybot.plugins.Anonymous.requireRegistration.
