Friedemann Kleint 87274e272d QtBase examples: Remove Maemo/Symbian-specific code.
- 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.
