- add i18n/closure directory with closure i18n files and
update-closure.sh script to update them
- generate.sh script runs node.js scripts that extract localization
rules from the closure library, transform them to a more suitable
format and dumps them into i18n/locale directory as angular's $locale
services
- update Rakefile to copy i18n files to build/ and pkg/ dirs
- copy i18n stuff during rake build
- e2e tests for several locales
