Title: Uniqueness validator

- Supports :scope and :case_sensitive options
- Included en.yml locale file for testing, since the generated error messages
are expected to be defined in a locale file (when passing in a symbol as the
second parameter to errors#add)
- See https://github.com/rails/rails/blob/v4.1.4/activemodel/lib/active_model/errors.rb#L381-L404
