Add note to QMessageBox::button() about modifying returned button

Browse Source 
We don't have a good way to detect whether the button is modified or
not, to bail out of using the native dialog helpers.

Document that this API shouldn't be used to modify the standard
buttons (they are standard after all), and recommend the explicit
APIs for adding custom buttons instead.
