This commit also cleans up a bunch of pointless noise each time we boot app
- narrative was loading i18n cause redefinition of consts
- discourse.rb was loaded twice as was auth
- bin/unicorn now does all the smart things and boots unicron in dev
- bin/rails s will boot unicorn with no params
- remove bin/puma which only causes confusion
Commit b516ecc added `bin/` to the .gitignore file. Now that Discourse
runs using Rails 4 by default, however, we should include the binstubs
generated by `rake rails:update:bin` in version control as this is the
recommendation of the Rails core team. Additionally, for those wishing
to deploy Discourse to Heroku, these binstubs are actually mandatory
according to [this article](https://devcenter.heroku.com/articles/rails4).
Other binstubs can continue to be ignored.
