docker support for running awestruct.

How to use:
  install docker, run:

  $ cd jbosstools-website
  $ docker build -t jbosstools-website  .

  This will run the full docker build (takes a while the first time).

  Now you can just run

  $ docker run -it --rm -p 4242:4242 -v `pwd`:/jbosstools-website -t jbosstools-website

  And it will run awestruct in isolation but on top of your changes in jbosstools-website.

  Content will be available at http://${DOCKER_HOST}:4242
