Permit signals to be emitted in a different thread

The QQmlNotifier approach to connecting to signals did not
support the cross-thread signal/slot model used elsewhere in
Qt.  This change allows one specific case of that - emitting
a signal in a different thread than the one the QObject
lives - to work.
