dequis 1edfcedda1 Receive 'self messages' in the right query window
Original patch by hondza <sedaj2@gmail.com>, from FS#833. I applied
several needed style changes, and rebased to current HEAD.

This implements the IRCv3.2 self-message extension partially (we can't
announce its support through CAP yet). This is also the format used by
the 'privmsg' znc module, and is already implemented by several other
clients.
