Remove obsolete locale files that are not found in Google Closure library.
I don't know why they were removed, but without a link to Closure we can't
maintain these files going forward so I'm deleting them.
BREAKING CHANGE: some non-common region-specific local files were removed.
Modify the script that writes the locales so all characters above \u007f are escaped
Includes the updated locale files after running the closureI18nExtractor.
Closes#2417
