As proposed by Emerson Macedo on dev list, it would be useful to have keywords for different languages pre-configured.
An I18nKeywords that reads keywords from I18n resource bundles for different Locales should do the trick.
We can provide i18n bundles for the most common locales in our core jar (very small overhead in terms of size!), and users can add or override them as needed.
The localisation should be done when instantiating the Keywords class so it only happens once.
