UI: Add WaitConnection() helper func

Browse source 
A helper function used with QMetaObject::invokeMethod which allows the
ability to use Qt::DirectConnection if on the Qt UI thread, or
Qt::BlockingQueuedConnection if on another thread to ensure that
regardless of what thread the invokeMethod is called from, that it will
wait until the invoked method has been called.
