Subject: [PATCH] fix(ngLocale): fix i18n code-generation to support get_vf_,
 decimals_, and get_wt_

The updated Closure I18N code relies on these methods to enhance the localization quality.

This fix prevents ngLocale files from referencing undefined values. In the short term, this
means adding references to versions of these methods in locales where they are necessary.
