DEV: use unicorn in development

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

bin/unicorn
