Introduced in branch:

Description: 

Locale module related data such as number of plurals and plural forms was removed from the language schema / objects. Two new variables were added to store this data: locale_translation_plurals and locale_translation_javascript. These are expected to be moved to the configuration storage system later when it becomes available.
