0.2.0

0.2.0
-----

* **This version introduces breaking changes!**
* `Client.kill`, `Client.remove_container`, `Client.remove_image`,
`Client.restart`, `Client.start`, `Client.stop` and `Client.wait` don't support
varargs anymore.
* Added commands `Client.top` and `Client.copy`
* Added `lxc_conf` parameter to `Client.start`
* Added support for authentication in `Client.pull` (API version >=1.5)
* Added support for privileged containers.
* Error management overhaul. The new version should be more consistent and 
* All methods that expected a container ID as argument now also support a dict
containing an `Id` key.
* Added license header to python files.
* Several `README.md` updates.

### Bugfixes

* Fixed several bugs with auth config parsing.
* Fixed a bug in `Client.push` where it would raise an exception if
the auth config wasn't loaded.
* Fixed a bug in `Client.pull` where private registry images wouldn't be parsed
properly if it contained port information.
