Setup and startup scripts

* Instead of fetching the setup script using curl, use the locally
  available script

* Create a startup script which starts mysql and apache, and then opens
  up an interactive bash shell so that the docker container won't spin
  down. We can also do this using `apache2 -D FOREGROUND`, but using
  bash instead lets us connect to the container again to see what's
  going on

* RUN mysql with the setup script, because at this point we have no
  mysql daemon to connect to

* Add environment variables/setup for apache
