Use libqpe's StorageInfo class for storage tab. This 1. reduces executable size by ~10% and 2. should now recognize MMC cards on iPaq's (can't verify myself, let me know if it doesn't work). Also added QScrollView on version tab so all info is visible when screen is landscape or input method is visible.
