Make strings translatable

I am working on it.

Translation added.

Thanks, @samit.310@gmail.com - Good patch, however, since I'd like to make these configurable anyways, I added some new code to the dev branch for a config form, save the strings as config, and added code for the translations so they work with core config translations. If you want to take a look, I'd love a second pair of eyes. I'm adding a few things to the dev branch like other fixes from other issues on here as well.
