Added Dockerfile, services.sh and modified README

How do I delete the broken one I first added?
```
(airmozilla)peterbe@Peters-MacBook-Pro:~/airmozilla ((d946e7e...) %)$ docker run -d -p 8000:8000 --name web -v /Users/peterbe/dev/MOZILLA/AIRMOZILLA/airmozilla:/airmozilla airmozilla
2014/11/03 11:44:49 Error response from daemon: Conflict, The name web is already assigned to 81c1d99461f4. You have to delete (or rename) that container to be able to assign web to a container again.
