Protocol reference

Control port implementation was written based on multiple documentation sources.

Of course the bible is the Control Spec, published by the Tor project. The text version is a little bit easier to deal with compared to the HTML version, which was also used for this project.

Due to many questions left after reading these documents, the source code of Tor was also taken into account. It allowed the removal of deprecated commands, replies or events when they were removed a long time ago, or are sometimes described in the documentation but were never implemented.

This hopefully ensures a better match between our implementation and the real protocol in Tor.
