cb.sendNotice(message, [to_user], [background], [foreground], [weight], [to_group])
===============================================================================================

Send a message to the room. If ``to_user`` is given, the message will only
be seen by that user. You can also use the optional params ``background``,
``foreground``, and ``weight`` to style your message. Only HTML color codes
(such as ``#FF0000``) may be given for the color stying, and the font weight will
only accept the options ``normal``, ``bold``, or ``bolder``. If you want to
provide styling options, but not a ``to_user``, just pass an empty string
to ``to_user``.

Text sent in your ``message`` will be truncated if it exceeds the maximum
length limitation of 48KiB. (49152 bytes)

You can use a ``\n`` inside the message to send a multi-line notice.

You may use ``:emoticons`` in the notice.

You can send a message to a certain category of users with the
optional ``to_group`` param. Just provide the color of which class of users
you would like the message to be sent to. Valid choices are ``red`` (moderators),
``green`` (fan club members), ``darkblue`` (users who have tipped 50 recently),
``lightpurple`` (users who have tipped 250 recently), ``darkpurple`` (users who have
tipped 1000 recently), and ``lightblue`` (users who own or have purchased tokens).
Keep in mind that many users will have multiple
categories applied to them, for example a fan club member who is also a
moderator will get messages sent with ``red`` and ``green``, even though their
name only shows in red in chat. Using ``to_group`` will always override ``to_user``.
