0.2.39 - compliance disclaimer, ClusterM-only credit

Compliance disclaimer added (issue #7): README and OrcaCloud page now say the bundled library embeds credentials that are not yours and that you alone are responsible for ensuring your use complies with the applicable terms and law. That warning previously existed only in the upstream fork readme.

extract_key_from_dump.py is now credited to ClusterM/open-bamboo-networking and its contributors, at the script author's request that he not be named or linked.
