'Send a "notice" to a channel or user.
Notices differ from privmsgs in that the RFC claims they are different.
Robots are supposed to send notices and not respond to them.  Clients
typically display notices differently from privmsgs.

@param sender: Who is sending this message.  Should be of the form
username!ident@hostmask (unless you know better!).

@param recip: The recipient of this message.  If a channel, it must
start with a channel prefix.
@type message: C{str} or C{unicode}
