Synchronize locale names with those that are used on Transifex and
  remove old locales (the Transifex locale names were recently updated
  to match the names that Mozilla uses).
Limit the locales that we ship to those for which we ship a localized
  Tor Browser. The list is defined via a new BUNDLE_LOCALES variable
  within localization/import-translations.sh (this is the same technique
  that is used by Torbutton).
Pull in recent translation updates.
