Change QProgressDialog to use the new soft key API.

The previous version created a new QAction every time setCancelButton
was called without deleting the previous instance. This version
stores the action pointer in the d-ptr, but still recreates it
everytime the button is changed.

Also, make sure the text is updated if setCancelText is called by
the user.
