This one can only play .wav files, but is far more stable than Phonon.
Any existing installations would auto-switch from Phonon to this one.
Any attempt to play a non-wav file would suggest switching to Phonon.
To enable portable version mode, simply create the portable/ directory in the
same directory where the executable itself lives. In portable version all
dictionaries live in content/, morphologies in content/morphology. Sound
dirs aren't supported in portable version.
