+ Added DistTar.py, creates nsound-A.B.C.[tar.gz|tar.bz2]
+ Added DistZip.py, creates nsound-A.B.C.zip

+ Added AudioStream::stepAverage(uint32 n_samples_per_step); degrades the
AudioStream

+ Added Buffer::speedUp(float32 x); resamples the stream by x
+ Added Buffer::speedUp(Buffer x); resamples the stream by x on a per
sample basis, note that a less than 1.0 value will really slow down the
stream, so the name is a tiny bit missleading.

+ Added AudioStream::speedUp(float32 x); calls Buffer::speedUp() accross
all channels
+ Added AudioStream::speedUp(Buffer x); calls Buffer::speedUp() accross
all channels

+ Added AudioStream::subStream(float32 start_time, float32 n_seconds);
