Remove i18n symbol dependency

date.order is the only key in rails i18n that is required to be a
symbol. This patch allows for symbols or strings which means:

* No requirement for symbol type in .yml files. A future
  YAML.safe_load wouldn't need to load symbols
* Rails could actually use json rather than yml as the backend
Don't change the original i18n data
Improve relation docs about to_sql and where_values_hash

* User class instead of Users.
* #where_values_hash does not change the value to downcase as the
  example was showing.
