Improved error reporting (thanks @johncosta) and don't encapsulate ports in a list in container_config
Fixed 'cmd' command in builder. container config now accepts command as a string or a list and converts accordingly.
Bumped version to 0.0.4
Support multiple slashes in client.push
Fix typo -- config is a dictionary

`self.config` is a dictionary, not an object. References to `self.config.Cmd`
should be `self.config['Cmd']`.
Python 3 compatibility: relative imports

In Python 3, this kind of import doesn't work any more. Relative imports have to
be explicit, as in this commit.
