Add a shortcut editor example

Many applications offer shortcuts for quick interaction with the
application. It is also common in such applications to offer a shortcut
editor in the preferences or separately in a dialog.

However, even though this is a fairly common use case for applications
with more than a couple of shortcuts, there is no good and comprehensive
official Qt example how this could be achieved.

This change is an attempt to bridge the gap.
