Rebase clean on top of master

[progrium]

Currently clean is based on release (1.5.0) because master was throwing errors. Could have been a mistake or transient error. Will rebase on master soon.

This would make integrating our work a lot easier, since it is based on (relatively) recent master.

https://github.com/squaremo/docker/tree/plugins-master has a clean branch rebased on master. It handshakes with plugins, but I need to find a three-phase power supply for my laptop in order to run the docker tests.

That's great, I was planning on doing this. Let me know how tests go. I'm not sure if the tests caught the panic I was seeing, but I can also just try your clean branch to see that it works with the plugin stub manually.

Argh, docker master is in upheaval as people remove the "job engine". Admittedly that really needed to be done.
