Other clients hang at "Waiting for Peer..." when attempting to connect to
jacktrip running as a server. This is because of a change to the way that
QHostAddress works in Qt5, resulting in the return of an IPv4-mapped address
instead of an IPv4 address. The attached a patch fixes this (restoring the
behaviour shown by Qt4).
