I made it fully translatable, waiting for your feedback

Hi Dan,

I left a response on my original review but didn’t get any feedback from you.

I did manage to make it fully translatable, as per your suggestion, including the few strings included in the JS file. I’m not sure how to do the pull-request, since your project on GitHub is not configured as a plugin folder.

Take a look at the i18n version.

Let me know what you think off it.
