Since this is a Rails application we should have a .ruby-version and optionally a .ruby-gemset in the root to deal with multiple ruby managers. With these two files in place it'll help with compatibilty with all of the main ruby managers - rbenv, RVM, chruby, etc.
Remove .ruby-gemset, not needed
Merge pull request #49 from nickhammond/ruby_setup

Add .ruby-version and .ruby-gemset to the application root
