- removed the remains of the FModEx-style stream implementation

Browse source 
FMod had MP3/Ogg playback integrated right into itself, and the OpenAL backend tried to replicate this functionality.

This functionality, however, has been removed over two years ago when FMod started breaking things more and more, it was only this backing implementation that was left in.
