As requested on #147, there is now an option to specify the Docker version to be installed when using the `docker_daemon` plugin. The version string is validated against a pattern extracted from the Docker's CHANGELOG. If the version is not present, it will just download the latest available. The download method was also changed from `urllib` to `wget`, so we can see its progress if needed. This closes #147.
