[Enhancement] Dockering the application to fix #179.

This commit adds initial implementation for deploying the current
code in a "Dockerized" container. That is, deploying the source-code
in a Docker container and being able to run it from anywhere with
the Docker runtime installed.

*	new file:   Dockerfile
- The Dockerfile containing the runtime installation process to the
  npm and bower dependencies.
- The parent Docker image will be already contain all the dependencies
  that allows users to run the current code.
- Exposing the default port 9000.

*	modified:   grunt/connect.js
- Changing the IP address from local to 0.0.0.0 in order to be able
  to be called from outside the container.
