Simpler start for development

[nixme]

Replace all those different process and commands to run with a single Procfile using foreman: http://blog.daviddollar.org/2011/05/06/introducing-foreman.html

Also see http://adam.heroku.com/past/2011/5/9/applying_the_unix_process_model_to_web_apps/

Then running the app should just be: foreman start
