Juce::BufferingAudioSource - Small Cleanup

Hi Jules,

Just noticed a class that is “friended”, but doesn’t exist, written in juce_BufferingAudioSource.h.

    friend class SharedBufferingAudioSourceThread; //<- This
    bool readNextBufferChunk();
    void readBufferSection (int64 start, int length, int bufferOffset);
    int useTimeSlice();


(According to the log, it seems that it predates JuceQuake, and hasn’t existed since JuceQuake was setup… :))

Ah, a straggler…! Thanks!
