- Maemo/Symbian are no longer supported and QWidget-based examples are no longer supposed to run on mobile platforms, so, remove any Maemo/Symbian or mobile-specific code from source files and profiles. - Remove Maemo/Symbian vibration examples. - Change Q_WS_MAC/WIN to Q_OS_MAC/WIN where appropriate.
