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
Action Pack already comes with a default locale fine for :en, that is
always loaded. We can just fallback to this locale for defaults, if
values for the current locale cannot be found.
Closes#4420, #2802, #2890.
Implemented support.array.skip_last_comma i18n key for
Array#to_sentence, this also tests the ability to store false.

standarize on. Also, in future this place can be used for data/code that's
not literally translations but conceptually belongs to the locale (like
custom pluralization algorithms etc.).
