update translation syncing to convert to Android folder names

Android has a special naming scheme for naming the folders that the strings.xml files for each language go into. It is like this:

• certain language codes sometimes have different names in Android, so there should be identical copies for each of these language locales:
  • he and iw
  • id and in
  • yi and ji
• there should never be a zh only locale, only zh with a country, i.e. zh_CN, zh_TW, etc.
• for a language-only locale: (e.g. de, es, mm), just add the language code to the end of values-, (e.g. values-de, values-es, values-mm).
• for a language+country locale (e.g. zh_HK, es_MX), convert the _ (underscore) to a -r (dash and lowercase R) and add that to the end of values- (e.g. values-zh-rHK, values-es-rMX)
