Both transports sent an empty string as the user modes in RPL_MYINFO.
On the IRC listener that left an empty parameter in the middle of the
line, so a client that splits on spaces read the channel modes as the
user modes. The reply now lists o and w, the user modes the server
supports, from one constant in pkg/irc that both transports read. The
README and the schema notes now show what the HTTP API sends.
