Updated changelog, bumped version in setup.py
Log streaming and correct decoding of multiplexed log streams

Implement log streaming with the stream parameter on logs(), returning a
generator of log lines based on the selected streams (stdout/stderr).
Also correctly decode the multiplexed log streams (current version was
buggy).
