Add core application functionality to Qt.application in QML

This exposes some information to QML which is available on
the QCoreApplication instance.

A future change should make it possible to restrict this for use in scripting
environments (which should not have access to the QCoreApplication). That has
been left out of this change because proper support for such restrictions is
not yet in place.
