extract-react-intl-messages

This is forked from extract-react-intl-messages. It removes un-used options (custom delimiter, exporting nested files, and yaml export), and adds an option to export messages in the same format that Chrome Apps use. We use this because the translation service we use, crowdin.com, accepts this format of file, and will include the description as context for the translator.

This package will generate json from a glob. It will generate one file per locale, with the ids of each message defined by the defineMessages function of react-intl. The value of each of these keys will be an empty string, or an object with the property message an empty string, except for your defaultLocale which will be populated with the defaultMessage.
