Can you make this two separate PRs? I will merge the changes to localization.ini right away... but we should discuss the changes to webi10n.js. That is an external library which we probably want to maintain upstream. But also, we are thinking about replacing it all together.

Got it! I will close this PR and open two separate ones as requested. Thanks for the clarification!
