This commit removes the key generation stage of building Anchor
containers. When a container is started it will look for a key in a
docker volume named '/key' if there is a correctly formatted key it will
attempt to use it. If not it will generate one before starting normal
operations.

I replaced the Dockerfiles that existed, which pulled anchor
down from git with a single Dockerfile that uses the local version
of anchor.
This makes testing local changes to anchor very simple.
I also updated the README to reflect these changes and fixed the
varying line lenghts within that file.
