Add a limit of 10 unidentified connections per IP

Everything which isn't a CClient with a successful login counts as an
unidentified connection in this context. Modules who don't want this kind of
limit on their listening sockets can override CSocket::ConnectionFrom(), but
their sockets will still count towards this limit.
