Project setup

- Added fresh rails project and made no changes. See 05c9a7b
- Added `.ruby-version` and `.ruby-gemset` so that [RVM will auto-switch to correct environment](http://rvm.io/workflow/projects#project-file-ruby-version). You should be using RVM to manage your environment. The benefits will be clear later on. Let me know if you need help. See 882e0c3
