Update the text editor to use the MessageDialog in qt quick dialogs

Our goal is to eventually remove the dependency for the qt labs platform
module. This patch will replace one of the labs platform MessageDialogs,
with a MessageDialog from qt quick dialogs.

All of the dialogs that are used in this example will eventually be from
the qt quick dialogs module.
