Subject: Adding QPlatformMessageDialogHelper and QMessageDialogOptions

We plan to add support for native message/alert dialogs on Android
and iOS because it's otherwise impossible to have a true popup window.
Then we might as well have native message/alert dialogs on other
platforms too.  It will become an alternative implementation behind
QMessageBox and perhaps QErrorMessage.
