Add support for 'cpuset'

Add directories to the Docker context

Added markdown docs for #83

* Fixed broken Dockerfile
* added .dockerignore

The command line and daemon started supporting --device
parameter during docker start a while ago in the following commit:
docker/docker@e855c4b

Since the command line looks like this,
--device=[] Add a host device to the container (e.g. --device=/dev/sdc:/dev/xvdc)
This patch allows a list of strings to be passed into the start() method
and we parse out the 3 components just like in the above mentioned commit

Catch invalid path in build method

This change adds both files and directories to the tra-file for the
Docker context. Previously only files where added.

The context will now also contain empty directoryes and symlinks
to directories.

It assumes you've got Docker running on /var/run/docker.sock, but
that should be the case on both Linux and in Boot2Docker.
