Fixed calling SoundStream::setPlayingOffset() unpausing a paused SoundStream (#203), guard m_isStreaming by a mutex, fixed calling SoundStream::pause() before the stream thread starts not properly pausing the stream (http://en.sfml-dev.org/forums/index.php?topic=15197.0), minor documentation fix in SoundStream.
