AudioDevices demo doesn't do anything on Windows

-put example audiodevices in layout.
-added more checking to testSettings() in win32 implementation.
-disabled objects in example audiodevices that are not editable.
-added more checking to alsa implementation for preferredFormat().
-changed internal strings from tr to QLatin1String.
