- Add support for https and auth identity
Allows use of DOCKER_CERT_PATH for TLS credentials to use for DOCKER_HOST,
as used by boot2docker.
This also allows for DOCKER_AUTH=identity, as used by nodes started by
docker machine.
- Remove core.async dependency
Fixes #21
- Use DOCKER_CERT_PATH to find client cert
- Use DOCKER_HOST to specify endpoint
For consistency with boot2docker, use the DOCKER_HOST environment variable
to specify the endpoint. DOCKER_ENDPOINT will still override DOCKER_HOST.
- Show the tag in 'Built image' output, if supplied.
