core (tools/common/template): i18n support - babel has been added as a new dependencies, and should replace gettext in core in the future - added i18n support in template rendered - current locale is available as babel Locale in templates through "locale" variable - locales can be changed before rendering using setLocale - for now, all locales translations are loaded on init, and stay in cache. A more complex cache system may be needed in the future (e.g. keeping only most used and load others from files when needed).
