Add unique object names for certain objects that are used in Release Test Automation

Please find attached the images of those objects that are needed in RTA testing. Like discussed earlier it would be good if the objects had an unique object name set so that when e.g. the Qt Creator's MainWindow changes (like what happened now in QtC 11 -> QtC 12) it wouldn't break the automated tests.

The Qt Creator MainWindow is the most important one to be named, since so many objects are related to that one.
