Title: Sanitize topic message

The code handling the topic message isn't expecting any new lines
since it is usually not possible to have any from the IRC specs.
But we can have some Unicode new lines instead!
Qt is happily converting them to simple new lines which then crashes
the client with a stack overflow.
