Channel modes

The MODE command is provided so that channel operators may change the
characteristics of `their' channel. It is also required that servers
be able to change channel modes so that channel operators may be
created.

The various modes available for channels are as follows:

       o - give/take channel operator privileges;
       p - private channel flag;
       s - secret channel flag;
       i - invite-only channel flag;
       t - topic settable by channel operator only flag;
       n - no messages to channel from clients on the outside;
       m - moderated channel;
       l - set the user limit to channel;
     b - set a ban mask to keep users out;
       v - give/take the ability to speak on a moderated channel;
       k - set a channel key (password).
