I18N support for popup.html. German and English. - #1874

Niiiice 👍

I think my only comment here is that you can/should remove the english descriptions directly from the html too.

From popup.html

<section id="UnstableRules" class="rules">
  <h3 i18n="chrome_experimental_rules"></h3>
  <p class="description" i18n="chrome_experimental_rules_description"></p>
</section>

If you do that, I think this should be good to merge :)

Ok, did that.

@jsha Any comments on this? Or am I good to merge it? :D

Thanks so much for your contribution! Merging this.

FYI if you're looking for a next task: I have a pull request #1351 that arranges for Chrome and Firefox to share the same translation infrastructure. This makes it easier for our Transifex community to contribute Chrome translations, and reduces overhead since many of the strings are the same. Feel free to pull that branch and start making the needed changes to make it compatible with this branch. Thanks again,

Jacob
